Source Picture Letterboxed for a non-letterboxed 4:3 title | Creating a menu button

I have a DVD that was created on January 26, 2003 by transferring a VHS
recording of a 4:3 non-letterboxed TV broadcast onto disc.

Two years ago (2012), I was unable to copy the disc with DVD Shrink, but
was able to do so with DVDFab DVD copy. I also excised a portion of the
film with Aiseesoft Total Video Converter, which is a free program I got
from the Giveawayoftheday site that I lost upon re-formatting, and saved
it in AVI format and VOB format.

One year ago (2013), I found that whenever I put this TV > VHS > DVD disc
in my Dell XPS 400 desktop PC, with an Intel Pentium D 830 CPU w/Dual Core
Technology @ 3.0GHz, 160 GB Serial ATA hard drive, and 3 GB Dual-channel
DDR2 SDRAM running Windows XP 32-bit, Service Pack 3, I would get the
Blue Screen of Death. I could play the AVI and VOB files that I'd made
with Aiseesoft Total Video Converter, though.

Just yesterday, I put the disc in my Dell XPS 8700 desktop PC, with an
Intel Core i7-4770 CPU @ 3.4Ghz, 2 TB 7200 RPM SATA Hard Drive 6.0 Gb/s,
and 16 GB Dual-channel DDR3 1600MHz RAM running Windows 7 Home Premium
64-bit, and I didn't get the Blue Screen of Death.

I ripped the disc to folders with DVDFab DVD Copy in Full Disc Mode, then
backed up several copies of the folders, and went into PgcEdit to experiment.

I opened one copy of the folders and saw this:

<<
Verify number of streams (in whole DVD)

! There are 1 audio streams defined for the menu domain
in the VTSI_MAT table of TVS 1.
0 audio stream are really used by the PGCs.

Fix the number of audio streams in TVSI_MAT to 0?
Yes | No | Yes to all | No to all
<<

I clicked on Yes and then saw this:

<<
PgcEdit: Open DVD

! The frame rate of the First-Play PGC is illegal !
Fixed to 30 fps (NTSC).
Please save the DVD...
<<

I clicked on OK.

I eventually found that if I did not change the Domain Streams
Attributes in Title 1, the resultant playback would display an
incorrect image with an Aspect Ratio of 1280 x 480 rather than 4:3.

Therefore, I changed the Domain Streams Attributes in Title 1 by ticking
the box named "Source Picture Letterboxed" to the right of Video: 4:3,
and the resultant playback displayed at the correct image with an Aspect
Ratio of 4:3, which corresponds to 640 x 480.

Subsequent attempts demonstrated that electing to edit the menu and/or
using DVD > Remove Useless Stuff had no effect on the Aspect Ratio seen
during playback.

I then ascertained that the original TV > VHS > DVD disc has an aspect
ratio of 1280 x 480. I hadn't realized this. Therefore, it must be
pointed out that while the source disc has an extreme letterbox-width
image, the image which appeared onscreen during the actual television
broadcast was not letterboxed. I assume then that the 4:3 (640 x 480)
aspect ratio is the correct one.

QUESTION ONE:
What I would like to know is why is it that I have to tick the box named
"Source Picture Letterboxed" to the right of Video: 4:3 in Domain Streams
Attributes when the source picture is in fact *not* letterboxed?

QUESTION TWO:
I would like to create a DVD that has the regular version of this film,
followed by the excised portion of the film that I saved to AVI and VOB
but is now also part of the copy of the TV > VHS > DVD disc I burned to
ISO with PgcEdit, so I was wondering if I can create a menu button for
this added Title after right-clicking on Title 1 and using the macros
afforded by Import Title's Intro Clip and Import Title's Closing Clip.

I intend on using the Import Title's Intro Clip macro to create a still
frame that instructs the viewer to press the »| (Next Chapter) button on
their remote once the film's credits start to play in order to see the
extended ending from the TV broadcast of the film, and then using the
Import Title's Closing Clip to add the extended ending itself.

It would be nice if I was able to alter an existent menu button or add a
menu button for this Closing Clip, though. Does PgcEdit allow for the
creation of such a menu button?

It's not really clear from your descriptions (sorry), but I highly suspect your source is actually representing a 4:3 frame (letterboxed or not doesn't matter right now) but is incorrectly flagged as anamorphic 16:9.

That option "Source Picture Letterboxed" can only be ticked if "4:3" is selected, which would flag the domain as being a 4:3 frame which would fix the error.
However, you actually also have to patch the aspect ratio in the MPEG stream (inside the VOBs) to make things compliant.

You should find that as long as 4:3 is marked, having the "Source Picture Letterboxed" checkbox ticked or not will result in absolutely no difference for PC playback.


If I was you I would demultiplex everything off your TV capture DVD, patch it, multiplex it with Muxman and then use PgcEdit to import it into your new DVD. You can add a new menu button to access the new content and edit the commands of the main movie to skip to it after the last chapter. To add a new button visually you would have to edit the menu's background in an image editing program.


Regarding the blue screens, the only thing I consider plausible is hardware failure (DVD drive or it's controller on the mainboard) or a connector problem.

Maybe this is clearer:

A) Original broadcast: 4:3 (640 x 480)
B) Source DVD: formats at 1280 x 480 in VLC Player
C) ISO and DVD-ROM after the box near "Source Picture Letterboxed" is ticked: 4:3 (640 x 480)

The 4:3 setting is insufficient to fix the error. 4:3 is the setting
which is automatically selected when the source DVD and/or its ripped
folders open inside PgcEdit.

Not so; I wish.

If I place the original disc into my PC, open VLC Player, and select
Tools > Media Information and click on the Codec tab, I see:

<<

Is this necessary? Is this why I got the "The frame rate of the

folders in PgcEdit?

Where do I find this in PgcEdit?

The menu that was created by the non-PC standalone DVD recorder has 11
buttons. Button 1 has the date of the recording and is clickable. Buttons
2-8 are blank but clickable. Button 9 is the Previous button and is
clickable. Button 10 is the Play button and is clickable. Button 11 is
the Next button and is clickable. Buttons 1-8 are full-length and in a
column, while Buttons 9-11 are each less than a third of the width of
Buttons 1-8 and are slightly below Button 8.

For some odd reason, the disc opens with Button 1 highlighted while all the
rest of the buttons are blank. The words Prev, Play, and Next only show up
when the cursor is placed over them. When I move the cursor away from
Button 1, the words "1...L...1...1/26/2003...4:04PM" disappear, too.

I think the video card might have been inadequate. My current machine
has an NVIDIA® GeForce® GTX 650 Ti 1.0GB GDDR5 video card.

I strongly recommend to avoid DVDFab to copy a DVD, especially if it is unprotected and already burned on a DVD-R. DVDFab skips silently any error it encounters, assuming that it's a protection. Unfortunately for you, the result is often a damaged disc. That may also explain the BSOD you got with some machine or players. (I recommend the good old DVD Decrypter when the DVD is not protected by a recent form of protection.)

The "Source Picture Letterboxed" should be ticked when the original movie (or "source") has the 16:9 aspect ratio but the Title on the DVD has the 4:3 flag set. In other words, when the 4:4 video has a small 16:9 image letterboxed into it, with horizontal black borders. When the "Source Picture Letterboxed" is ticked AND the player is connected to a 16:9 TV with a SCART connector, then the player is supposed to send a signal to the 16:9 TV telling it to zoom into the picture to hide the black borders and display the 16:9 part of the image in full screen. Unfortunately, many players or TVs ignore that flag, and therefore it is globally useless.

As explained by TheSkiller, your original movie was probably in 4:3 (with or without black borders) but the DVD recorder has erroneously set the 16:9 flag in the IFO. To restore the correct aspect ratio, it is normally sufficient to tick the 4:3 option in Domain Stream Attributes. (As recommended by TheSkiller, it might be also a good idea to fix the aspect ratio in the VOB files, for the (rare) players that take the AR in the VOBs rather than in the IFO, but normally you can skip that part, because the AR stored in the IFO has precedence.)

It is possible to create a simple button with PgcEdit, but it can only define the transparent clickable area and the colour and transparency of the rectangular highlight. In other words, you will not see the button when it is not selected. If the menu is a still image (with or without sound), you can save the background image as a BMP with the preview, edit it with any paint program and import it back in the menu with VobBlanker. It is also possible to export and import the subtitle containing the button highlights to edit the highlight of the new button. There are several guides explaining how to add a button to an existing menu available here at D9 or in other forums. Note also that you will have to edit the navigation commands yourself to call the right clip when the button is activated, and to return to the menu when the alt closing clip has finished playing.

You have replied to TheSkiller when I was typing my reply.

As I have explained above, the Source Picture Letterboxed flag usually doesn't work and is useless, and when it works, it doesn't change the aspect ratio of the movie. Ihe TV is supposed to zoom in the image to hide the black borders (if any), and nothing else. The image is not stretched horisontally or vertically.

There is no info about the aspect ratio here, so that doesn't mean that VLC considers the movie as 16:9 or 4:3. Anyway, VLC is probably the worst player to test a DVD. It is a good player except for the DVD, because it is not at all compliant with the DVD-Video specs. You should use another player, such as MPC-HC, to do your tests.

To patch the AR in the VOBs, use DVDPatcher. But I repeat that normally, it's not necessary (except perhaps for VLC). ;-)

Ignore the "The frame rate of the First-Play PGC is illegal" warning. It's a consequence of a little bug of many DVD recorders. The FP-PGC contains no video, and therefore many recorders assume that its frame rate is irrelevant, and omit to define it. But the DVD-Video Specs impose to define it. Hence the warning. Let PgcEdit fix it, and don't worry. (BTW, the warning about the number of streams is also due to a frequent little bug, without important consequences. You can also fix the problem and forget it.)

To create a new button, go to the menu editor. (Select the menu PGC, type Control-M to open the menu viewer, and click the Edit button. Then, use Button -> New button.) Be sure to fix the adjacent button links, and don't forget to assign and/or edit the colour scheme to make the highlight visible.)

Since your menu has already a lot of unused buttons, you can probably simply reuse one of them, as you have suggested yourself. To change the background, follow the instructions of one of the numerous guides on that subject. (I have typed "edit dvd menu background vobblanker" in Google and at least the 4 first hits should contain useful information.)

I downloaded DVD Decrypter and also DVDPatcher. Thanks for the suggestions.
I didn't reply right away because I read the DVD Decrypter Guide and Option guide
and took a little while to familiarize myself with the program.

I had trouble with DVD Decrypter until I set it to Windows XP (Service Pack 2) in compatibility mode.

Am I correct in surmising that DVDPatcher is not a program that actually installs -- that you simply run it "as is"?

I ran DVD Decrypter for the TV > VHS > DVD disc and the
results were identical to that of DVDFab Copy DVD.

I then tried running DVDPatcher and it worked fine for the 1st, 2nd and 4th VOB files,
but when I tried patching the 3rd (VTS_01_3), I got the following error:

<<
Please select a valid MPEG2 File.
<<

And in the pane in the right column, it said:

<<
no Sequenceheader found!
<<

I found this odd, so I went into the video folder DVD Decrypter made and found this:

VTS_01_1.VOB Length: 00:00:14 Size: 0.99 GB
VTS_01_2.VOB Length: 00:00:14 Size: 0.99 GB
VTS_01_3.VOB Length: 26:30:24 Size: 0.99 GB [not a typo!]
VTS_01_4.VOB Length: 00:00:10 Size: 77.9 MB

Going into PgcEdit, I loaded the folder, right-clicked on VTST 1, 1 TTN 1 (1:32:54) title 1
and selected Edit PGC.

At the top left, it says:

<<
Playback time 01:32:54.00 (at 30 fps)
<<<

Something is seriously screwed up with these TV > VHS > DVD files.

Re how to use DVDPatcher, all I found was was these two pages:
http://forum.videohelp.com/threads/1...te-Mixed-DVDss
http://www.youtube.com/watch?v=Ea8SgILT19Y

Is there any more information on DVDPather *in English*? (I found nearly a dozen in German.)

IIRC, yes, DVDPatcher has no installer and can be run as is.

You don't have to patch each VOB file individually. For technical reasons (related to limitations of the file systems), a VOB file must be less than 1GB. Since usually a movie requires more disc space, it has to be spread on several VOB files. So, in a DVD, the structure of the VOBs is something like this:
VIDEO_TS.VOB (Contains the "Title Menu" VOBs. That file may be empty or absent if the VMGM has no non-dummy PGCs.)
VTS_01_0.VOB (Contains the Menu for VTS 1. This file can be empty or absent if there is no VTSM menu or if it contains only dummy PGCs.)
VTS_01_1.VOB, VTS_01_2.VOB ... up to VTS_O1_7.VOB (Contains the Titles of VTS 1. At least VTS_01_1.VOB must be present and it must contain al least a short cell.)
VTS_02_0.VOB (Menu of VTS 2. Optional.)
VTS_02_1.VOB, VTS_02_2.VOB ... up to VTS_O2_7.VOB (Contains the Titles of VTS 2. Optional titleset. Only VTS 1 is mandatory.)
[...]
VTS_99_0.VOB (Menu of VTS 99. Optional.)
VTS_99_1.VOB, VTS_99_2.VOB ... up to VTS_99_7.VOB (All VTSs execpt VTS 1 are optional.)

So, in your case, you must consider VTS_01_1.VOB to VTS_01_4.VOB as one single big file that has been split into several parts. By default, DVDPatcher patches only the first nav pack of the first VOB file, but it has an option to patch all nav packs. If you tick that option, it will process the 4 VOB files automatically, and it will most certainly not encounter any problem.

It cannot patch VTS_01_3.VOB independently of the other VOB files for the following reason:
The DVD-Video specs impose to cut the VOB files at the beginning of a sector (or, in technical term, at a specific LBA). That means that the size of each VOB file must be a multiple of 0x800 bytes (or, in decimal, 2048 bytes). Many authoring programs prefer to cut the VOBs just before a Nav pack, because a nav pack is always placed before a GOP (Group Of Pictures) and the VOB file can therefore be considered as an "excerpt" of the big movie. VOB files that begin with a Nav pack are usually easy to play with any player, and can be successfully decoded. However, cutting before a nav pack is NOT mandatory, and many authoring programs cut the VOBs inside a GOP. When it's the case, the beginning of the VOB contains data from the video, audio or subtitle streams, and that doesn't make sense for a player. Therefore, that VOB files cannot usually be played by a player, because the player expects to find a nav pack, that acts as a "header" containing useful information to correctly decode the next blocks.

Of course, the first VOB (VTS_01_1.VOB) must always begin with a nav pack, and most players are smart enough to consider the next VOB files from the same VTS as the continuation of the first one. So, if you play the third VOB file directly, most players will fail, but if you play the first one, they should be able to go on and play all VOBs from the whole VTS correctly, including the third.

Of course, it doesn't make sense to display the length on an individual VOB file. The duration displayed by the program will either be the duration of a single VOB only, or will be completely wrong if the first block of the VOB file is not a nav pack, but the program tries to interpret its content anyway.

You haven't specified which program you have used to display the wrong length, and I guess it's the Windows Explorer. Anyway, don't worry. Explorer tries to interpret the content of the VOB file as if it was a standard MPEG 2 video file. As you know now, it has many reasons to fail. (And, BTW, the displayed length of 00:00:14 are obviously wrong too.) PgcEdit is right, because it takes the structure of the DVD-Video into account when it displays the duration of a title. (And anyway, the duration is retrieved from the IFO and not computed from the VOBs.)

If you want to examine how a nav pack is made, use VobEdit. (But take care: any modification you do with that program is saved immediately, without confirmation.) I'm sure that you will see that the third VOB doesn't begin with a nav pack. If you want to cut all VOBs at a nav pack, you can open your DVD folder in DVD Shrink, and save it elsewhere without modifications. DVD Shrink cuts the VOBs at the nav packs, but I repeat that it's not mandatory.

In short, don't worry. Unless DVD-Decrypter has explicitly displayed some warnings or error messages during the rip, you can be sure that the rip is good.

Are you referring to the very bottom left field of the DVDPatcher window,
which is Patch, with the choices "First header only" and "Entire file"?

Sample DVDPatch window from videohelp.com <http://www.videohelp.com/toolsimages/dvdpatcher_154.jpg>:



I was able to select "Entire file" and patch VTS_01_1.VOB, VTS_01_2.VOB and VTS_01_4.VOB
individually, but not VTS_01_3.VOB.

Why does it allow me run the patch manually for VTS_01_1.VOB, VTS_01_2.VOB and VTS_01_4.VOB, then?

In other VOB files I've looked at (from different DVDs), the duration in minutes is listed correctly.

Yes. From Windows 7 Home Premium, Service Pack 1.

DVDPatch did not patch the aspect ratio of the DVD, by the way. The ISO file
that I created presented the VOB files at the correct aspect ratio when played in
VLC Player, but that was only because I had altered the aspect ratio by using
PgcEdit to tick the "Source Picture Letterboxed" in Domain Streams Attributes.
The ISO file opened in VLC Player at the incorrect aspect ratio (before changing
for the sake of the 4:3 menu screen).

I then tried running DVDPatch with the VOB files at the incorrect aspect ratio
(i.e. unaltered by PgcEdit), and the results were an ISO file where the VOB files
display at the incorrect aspect ratio and VLC Player starts up at the incorrect
aspect ratio, too.

The only thing that works to make the files in Title 1 display correctly is using
PgcEdit to change the Domain Streams Attributes in Title 1 by ticking the box
named "Source Picture Letterboxed" to the right of Video: 4:3.

For the sake of thoroughness . . .

This is what VLC Player looks like before the menu loads <http://i57.tinypic.com/scb0pl.jpg>:


This is what the menu looks like when it loads in VLC Player <http://i58.tinypic.com/ng2e6f.jpg>:


This is what the movie looks like in VLC Player without the aspect ratio corrected <http://i59.tinypic.com/6i40so.jpg>:


This is what the movie looks like in VLC Player with the aspect ratio corrected <http://i57.tinypic.com/oh44dg.jpg>:


This is what the movie looks like in PgcEdit <http://i58.tinypic.com/2wrlz5l.jpg>:

OK, it's a 4:3 movie, without black borders. So you MUST select the 4:3 option in Domain Streams Attributes and TURN OFF the source picture letterboxed option. (Have a look at the Domain Stream Attributes of the menu. It is OK, and you should probably use the same settings for the movie.)

If VLC insists to display it incorrectly, just use a good media player. I have always encountered a lot of big bugs with VLC. It's an excellent player to play standalone video files and for the streaming, but it is extremely bad to play DVDs. The extremely large window displayed above is an evidence of the bad quality of VLC: that aspect ratio doesn't exist in the DVD specs, and should therefore never be used when a DVD is played.

Do NOT use VLC to test if your DVD edits are correct, as it will probably lead you in the wrong direction.

It's streched out to approx. 2.35:1 in VLC, which makes me suspect the Sequence_Display_Extension (SDE) in the VOBs is set to some (odd) value. I know for a fact that VLC does include SDE in it's aspect ratio decision, whereas other players, and hardware players, pretty much all ignore it and just follow the IFOs.


Stephe, can you please load one or all of the main movie VOBs into DGIndex (comes after HCenc, "DGMPGDec"), hit Play (F6) and report what the info box says at "Frame Size", "Display Size" and "Aspect Ratio"?

This one (I hope hank doesn't mind direct linking) "Download DGMPGDec 1.5.8", extract it, run "DGIndex.exe" and then drag and drop a VOB of the movie into it, confirm with OK. Then press F6 and a big info box will pop up.

That's interesting. The Sequence_Display_Extension is set to 720 pixels while the encoded frame size is smaller than that, being 704x480. That's not how it's supposed to be, because the SDE has to be less than or equal to the encoded frame width, or undefined. This might trigger VLC Player's behavior.

To fix it the VOBs would have to be demuxed and then the SDE can be patched or removed using Restream or ProjectX. Well, and after that things need to be re-authored using Muxman for example, then and re-inserted into the original DVD (optional) using VobBlanker or PgcEdit.

... or, as I have suggested, you can just use a player that obeys the DVD specs and takes into account the information from the IFO, that has always precedence.

I agree. VLC is a good media player but it really sucks at playing DVD structures in many ways.

Thank you r0lZ and TheSkiller.

Lesson learned. I will no longer rely on VLC Player to test aspect ratio correctness.

I really only have VLC Player on my new Windows 7 machine instead of PowerDVD or WinDVD because of its screen capture capabilities (which aren't great but are better than that of PowerDVD or WinDVD).

WinDVD 8, which worked on my Windows XP machine, had great screen capture capabilities (allowing you to back up about a dozen frames and then advance one frame at a time) but WinDVD 8's patch is no longer supported by the manufacturer (Corel) and therefore the patch didn't work after I reformatted my PC. (WinDVD 8 still worked, but the WinDVD 8 patch, which greatly improves image quality, didn't.) WinDVD 8 also won't work in Windows 7.

I bought WinDVD 11, but found out the hard way that while WinDVD 11 Pro works in Windows 7 and 8, the plain version of WinDVD 11 works only in Windows 8. And its screen capture is no longer remotely as user friendly as it was in WinDVD 8. I was reimbursed by Corel.
