[mythtv-users] HD playback with xvmc

[Welf]

I'm having some trouble getting HD content to playback using xvmc on  
a VIA EN1500 with the CN700 chipset using revision 11012 of 0.19- 
fixes branch of svn.  SD content plays back using xvmc just fine.

However with HD content it seems that my frontend is unable to find a  
suitable xvmc surface and instead falls back to libmpeg2.  Does  
anyone have any insight to this?
