Comment 6 for bug 585263

I have since established that my VDPAU setting was wrong. I have an NVidia 8400 card and had the setting set to VDPAU high quality not VDPAU normal.

from http://www.mythtv.org/wiki/VDPAU .........

VDPAU Playback Profiles are automatically created in current versions.

VDPAU High Quality: use Temporal Spatial 2X (Advanced 2X) for all content. To be used with nvidia cards >= 8600GT, >= 9500GT, GT120 or >= GT220
VDPAU Normal: use Temporal 2X for HD content, and Temporal Spatial 2X (Advanced 2X) for SD content. To be used with nvidia cards >= 8400, >= 9300, GT110 or >= GT210
VDPAU Slim: use Bob 2X with skip chroma option, with One Field as fall back, to be used with nvidia cards >= 8200 or when VDPAU Normal doesn't work for some reasons.

So the picture is now fine but I still get the error in the logs.
