[mythtv] XvMC Support broken in Latest SVN

Yes, I'm having the exact same problem.   It's something very new, as the
Sunday night (1/22) SVN (just after Chris Pinkham's network control update)
was working just fine, and it died just following a svn update last night
(1/25).  I'm currently rebuilding everything in debug mode so I can get a
good backtrace.

I see the " VideoOuputXv Error: Could no open XvMC port..." as well as some
mpeg errors sometimes.

Subject: [mythtv] XvMC Support broken in Latest SVN

I have pulled tonight SVN and the XvMC support seems to be broken
As soon as you go to watch live tv it kills the frontend
In the log from the console it shows
VideoOuputXv Error: Could no open XvMC port...

I did have a big gentoo emerge today as well so it could be something  
else that is broken.
Anyone else having any problems

Regards

Tim
