Eric,

I maybe very wrong here but from my reading of the following log output
mplayer is failing on VDPAU output and falling back to ffmpeg libavcodec
implementation for  playback and not using vdpau.

<snip>
Opening video decoder: [mpegpes] MPEG 1/2 Video passthrough
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
VDecoder init failed :(
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Unsupported PixelFormat -1
Selected video codec: [ffmpeg2] vfm: ffmpeg (FFmpeg MPEG-2)
</snip>

HTH,
Ben
