Just uploading the sample to

Summary of my testing


Playback has no issues when using Jean-Yves build of mplayer

  mplayer -vo vdpau  -vc ffh264vdpau -mc 2 /myth/tv/ 
12001_20090524120306.mpg

Also plays without issue with the software ffmpegh264 decoder.


Current testing environment  for MythTV

     * Ubuntu 8.10
     * NVidia VDPAU 185.19
     * mythtv - 1:0.21.0+fixes-20550-openglvdpau-debug-0ubuntu2

Initially my profile was

     * Enable OpenGL Timing for VSync - off
     * Video Playback profile VDPAU
     * Deblocking loopfilter off
     * Max CPUs 1
     * Deinterlacer - Temporal (1x,Hw), no fallback

Changing OpenGL Timing for VSync to on made no difference, as did  
enabling the loopfilter.

I then worked through all of the VDPAU de-interlacers, including  
turning the de-interlacer off and the corruption remained.

Next I tried the ffmpeg standard decoder with XVideo and vdpau  
rendered, both of which worked without issue and showed no macro  
blocking.


Jean-Yves - I'll be very interested to hear how well this works for you.

Steve
