I'm not sure why BD-RB assumed it was 4:3. I'm guessing, maybe, it lost it in the conversion??
Not 4:3, 3:2. It considered the pixels to be square, which they aren't.

You can force 16:9 by adding the following to your INI (see HIDDENOPTS.TXT):

IMPORT_FORCE_ASPECT=16:9
Didn't work, still 3:2.

Make sure you reenable framerate conversion before importing it
I have no clue what that option is. I couldn't find any option with "framerate" in its title.
Quote:
-- and don't forget to comment IMPORT_FORCE_ASPECT out or delete it after you import that file, though, so you don't ruin the next import.
Impossible. The options are used for the whole run, which in this case is five 720x480 files and a 1080p file. I'm assuming that a comment in the INI file is a "!" character.

If the framerate is variable, I doubt it came directly off a DVD, someone had to convert/reencode it first.
True, since BDRB won't read in VOB files directly. So, the first file I worked with is the MKV created by DVDFab. Looking at the VOB file with mediainfo, it declares the framerate as 29.97. But, DVDFab gets it right in that it is 23.976 with 2:3 pulldown. When I look at the VOB file with VideoReDo, it honors the pulldown flag and when stepping thru the video it displays four and then skips a frame. I used TSMuxer to create a TS file of the VOB file. TSMuxer declared the file to have pulldown. That file does not indicate variable framerate when looked at with mediainfo. But, BDRB still says that it has VFR. So, it also set the framerate at 59.94. By turning off VFR, it again did the frame rate as 19.181.

If you still have issues, send me a short clip (dvd-rb@jdobbs.net) and I'll trace it during import. I made some changes to the import algorithm recently and there may have been some unforeseen impacts.
I've sent you an e-mail with a couple of links.

The DVD VOB file should be able to be dropped onto a Blu-ray, since MPEG-2 with 2:3 pulldown flags should be legal. Actually, any VOB file on a DVD should be able to be dropped onto a Blu-ray.
