when using VDPAU as the renderer for playback of a certain .mkv file, I'm getting a mostly-green screen with lots of digital artifacts. Software renderer works fine. File is a bluray backup (from my disc) of Shaun of the Dead, encoded using MeGUI.

info:
-h264/dts in .mkv
-1880x820 res
-Camelot Beta 2 PPA, default skin (problem occurred in b1 as well)
-nvidia 190.42 drivers
-XBMC Live 9.04 install on HDD
-x86

Debug Log

hopefully I didn't miss anything

mediainfo output Smile

mkv is a container and tells us nothing about the actual video content format.

1880x820 is an unsupported width on VDPAU feature-set-B cards (ie on Ion).

It's a silicon problem i'm afraid, so there is no known work-around.

gotcha, I thought I had remembered reading about this at one point. In the future I'll just be sure not to crop off the sides and just leave the width at 1920

Sigh. low, medium or high profile, cabac or no-cabac, number of ref frames, bit rate. The list goes on....

h.264, profile 4.1 is not enough info to fully describe the video encoding.

fair enough, next time I'll include the mediaInfo output as well.
