I do NOT have a grey frontend, so what's option B for figuring out
whether XvMC is working? My system seems to play HD content alright
when the CPU load is fairly low, but if it's commflagging or
transcoding, the prebuffering pauses start to add up. I've followed
the wiki as best I could, but it's a bit out of date for newest svn.
I THINK using the CPU+ profile, XvMC should be enable if it's working,
but I'm not positive.
The log seems to indicate maybe it's not:

I'm not sure where xvmc-blit should be coming from.
