 I'm using trunk r23312 and did not see this issue with a checkout about
 two weeks ago before the recent vdpau changes.

 Playing h264 content, my cpu usage is 1-2% as expected.  When playing
 mpeg2 (hdhr and fw stb recordings), my cpu usage is about 22%.  Using the
 ffmpeg decoder, cpu jumps to 55%.  Logs show vdpau is being used and there
 is a definite difference between vdpau and ffmpeg decoders.

 I'm attaching logs with '-v most'.  The mpeg 2 log is tv.log and the h264
 is video.log.  My nvidia drivers are 195.30 and my card is a 9400 GT (G96)
 with 1GB.
