Re: VDPAU 9400GT MPEG2 artifacts
Same problem here in german cable (MPEG2 stream) with Gainward 9400GT (passive).
I have tested the newest 185 and 190 drivers on Debian Lenny Kernel 188.8.131.52 (xine-vdpau- and mplayer-SVN). Corrupted blocks seems to be decoded already - they look like old memory content.
Sometimes there are minutes with no corruptions and then periods with some blocks every 2 to 10s. Most of the blocks appear in scene changes. I have absolutely no problems with VC1 or H264 encoded streams - deinterlace option does not matter. If I decode the same stream with xv everything is fine. By using mplayer with -vc ffmpeg12 option everything is OK, then with -vc ffmpeg12vdpau the blocks appear.
