[mythtv] PATCH: program guide freeze on XVMC

[Curtis Stanford]

After the latest patches to videoout_xvmc.cpp, the program guide hangs 
when presenting the small video window. Not the hard hang like before. 
I can ssh in and kill it. Anyway, after patching videoout_xvmc.cpp with 
the following patch, it's all good again.
