[mythtv-users] No HD playback on OPENGL, xvmc-blit' not available

Ever since upgrading from 0.20 to 0.21 and rebuilding my separate 
frontend/backend setup OS, HD content won't play normally. The preview 
window works fine, the audio works but the video is just blank.

HD content used to work prior to upgrading. The frontend I'm is using 
consists of the following ...

NVIDIA driver ( NVIDIA UNIX x86_64 Kernel Module  180.51)
MOBO: ASUS A8N-VM CSM using onboard graphics chip
Standard Debian testing build (2.6.26-2-amd64)

Myth version from debian-multimedia (unstable, also tried originally on 
testing)...

mythfe-lounge:/var/log/mythtv# mythfrontend --version
Please include all output in bug reports.

The preview window shows the content fine. Also, mplayer plays demo HD 
content fine.

Can anyone assist finding the fault here? It appears only when Myth 
tries to play the HD content that it trips up. It looks to be that its 
defaulting to OPENGL and for some reason, can't actually display content 
in this fashion

Log file as follows..
