With madVr I can't play FRAPS video (no matter if YV12 or RGB), it doesn't show any image.
Tested with MPC HC and its internal decoder and also LAV.

Any idea what's causing these lines? Is this pointing to a problem with my graphics card?

My graphics specs are
Code:
Operating System:	Windows Vista (TM) Ultimate, 32-bit (Service Pack 2)
DirectX version:	11.0 
GPU processor:		GeForce 8600 GT
Driver version:		285.62
DirectX support:	10
CUDA Cores:		32 
Core clock:		540 MHz 
Shader clock:		1188 MHz
Memory clock:		700 MHz (1400 MHz data rate) 
Memory interface:	128-bit 
Total available graphics memory:	1279 MB
Dedicated video memory:	512 MB GDDR3
System video memory:	0 MB
Shared system memory:	767 MB
Video BIOS version:	60.84.41.00.00
IRQ:			16
Bus:			PCI Express x16
If you're using HDMI it's possible that you're not getting full RGB output (0-255) if you're using an HDTV resolution (e.g. 1920x1080 vs. 1920x1200). But that screenshot looks far worse than that. Are you sure you have color bit depth set to 32-bit, and not something like 16-bit?

Yes, I am definitely using 32-bit color depth (True Color).

And your right I am using HDMI at Limited RGB at 1920x1080 (I thought that was preferred for TV/Video). I'll do some tests later at full RGB.

Which app did you use to show that GPU info?

Open the NVIDIA control panel. In the bottom left hand corner there is a System Information button which will show you that info in a tab.

I don't think NVIDIA has that setting. AMD has two, one it calls "pixel format", which affects everything, and the other one is in the video section and is called "dynamic range" and only affects certain renderers like EVR, and madVR only when using DXVA2 deinterlacing. NV only has the latter.

What you need to change to RGB Full is the equivalent to "pixel format" which unfortunately for some (most?) people requires a PC resolution, or doing a custom HDTV resolution.

@entrecour Before you go chasing rainbows and making or testing a bunch of settings, I want you to know that I tested on my setup and the grayramp.ytp looks identical with my card. To test for gradient transitions, try looking at the smallramp.ytp or just get a regular grayscale ramp test pattern, such as the one from the AVS HD 709 calibration disc or MP4 files. You can easily tell when dithering isn't being used on a pattern such as this.

I was about to post the same until I read you already did.

Yes, you remind me that the NVIDIA fullrange (0-255) settings are messed up - if I use those whilst it does make a change of some sort I can't get the flashing bars in the AVC black levels test.

Every time I have tried setting up a custom resolution in the past my TV doesn't like it and I had to plug in another monitor to reset, so in the end I left it at the 1920x1080 native HD setting. I guess I can have another shot at it though.

Thanks, that's good to know. I tested smallramp.ytp and the ramp in AVC (see screenshots below) and I think they look OK, there are somelines visible but nothing as horrible as with greyramp.

I have gone back to .79 again. It seems when I find one fix it brings up other issues. It seems with .80 I have to use the old render path with 25hz material on a 50hz display and the new render path for 23.976 material on a 23.976 display. All in all it seems for what ever reasons 080 gives my system problems filling the backbuffers. Going back to 079 and all is well again.

Razoola, did you already try "limit rendering times" in madVR options?

Yes it does help but not totally. Basically it all boils down to the present queues not filling in .80 like they do in 079 when using identical settings with 25hz material at 50hz. 23.976 is fine.

Ya know, the present queue doesn't have to be full, as long as its above 0 and there are no drops.

Yes I do and here is where the problem is..... in 079 it does not really drop and if it does dip it never goes to zero. In 080 it does drop, quite often at and hits zero at regular intervals.

If anything that seems to be beneficial. I'm far more likely to get presentation glitches when the present queue is full rather than not. In fact, I suspect that if the "limit rendering times" option limited them enough that it would never fill up, it might fix my problems—your suggested flush settings really helped, but didn't eliminate presentation glitches with longer videos.

Gah, I (hopefully temporarily) bricked my 5770, reporting here that the good old 4670 is working fine with madVR's new options too! I miss the "dynamic range" option in CCC though, anyone knows if this can be accessed with DXVA Checker and which setting it is? I have 3 settings that say "dynamic range", but they don't seem to do anything. Also, I'm running Win 7-64, but I assume with madVR I have to run the 32-bit DXVA Checker version, right?

I have Dynamic Range disabled at default in CCC? should be to better enable it? and how about those options on video quality in CCC? do they affect to madVR or final quality in anyway? better to disable it? or does not matter either enable/disable as for MPC-HC/masVR playback?

with 0.80, when switching between deinterlacing and no deinterlacing, theres still the difference that colours look more vibrant when deinterlacing is off compared to when it is activated (or the other way round, colours look more washed out with active deinterlacing). is this how its supposed to be? it looks like as if levels get set to TV when deinterlacing is active in these cases.

Deinterlacing will most likely activate your video cards post-processing. Just make sure everything is turned off in the video cards control panel.

It's recommended to enable it and leave it at 16-235, but with madVR this will only affect DXVA2 deinterlaced content. If you keep it disabled, in my experience there's no telling what the driver will do by default, and can change with different drivers and maybe different players.

All those other video processing options, if they work they do only when deinterlacing as well, like nevcairiel said above, and most of us disable them.
