When playing MPEG videos using mplayer and vdpau, the video quality is really bad.
I think there is a problem with ffmpeg12vdpau.
mplayer -vo vdpau -vc ffmpeg12vdpau
plays the file but the video quality is terrible
mplayer -vo vdpau -vc ffmpeg12
plays the file correctly
All other video formats play correctly.
I have uploaded the log and sample file to the ftp server as explained in the sticky.
