#74: CN400 chipset cannot reliably playback HDTV content using XvMC

 I'll attach the following log files:
 In each application 1 log for non-HD content (480i/p) 1 log file for 720p
 HD and 1 for 1080i HD content.
 mplayer always using -vo xvmc -vc ffmpeg12mc
 xine always using -V xxmc
 mythfrontend always using the -v playback and VLD XvMC option

 The problem is:
 When I try to playback either a 1080i or a 720p program on an SP13000
 using the VGA output, I get the following results:
 * In Xine I get a black screen with smooth audio on 720p content, and a
 black screen with stuttering audio on 1080i content.
 * In MPlayer I get video, but no audio with either the 1080i or 720p
 content, but I do get an picture.
 * In MythTV I get horribly stuttering video and audio with 720p content,
 and just stuttering audio with 1080i content.

 In all of the above I get smooth image and audio with 480i/p content (from
 a ripped DVD vob).

 If any other information is necessary I'll be happy to provide it.  I
 chose to test and attach logs from all 3 players to give a more rounding
 understanding of what is going on, hopefully it's not overwhelming or
 confusing...
