[mythtv] XVMC in latest CVS

[Chris White]

I've just bit the bullet and upgraded my Knoppmyth R5A12 system to 
latest CVS, hoping to get XVMC working somewhat better. Everything went 
fine, until I finally tried XVMC, and it failed rather spectacularly 
when going to play a program (though the previews seem to work, do those 
use xvmc?)

Here's the relevant playback log:

For what it's worth, I'm running an nvidia 5200 with driver version 6629.
Any thoughts?

Thanks,
