 XvMC on nVidia hardware, and in my playback profile I have xvmc-blit, but
 in the output logs mythtv will show that is falls back to opengl. What do
 I need to do to prevent that? None of my playback profiles have the opengl
 video renderer selected. I am attaching the myth.log from this run.

 I figure out why it was falling back to the opengl renderer. My machine is
 one that can just barely play HD content, and only if I use XvMC. What I
 had found was that with all of the changes that had been made to the
 playback profiles, and using XvMC libraries, that if I used the --xvmc-
 lib=XvMCNVIDIA --enable-opengl-video --enable-xvmc-opengl option I could
 get my machine to play HD. If I only include the --xvmc-lib=XvMCNVIDIA
 option then it correctly uses the xvmc-blit renderer and I don't get this
 segfault, and I can play HD.

 So this segfault does exist, but may be fixed in the -vid branch, it is up
 to you if you want to leave it open and try and fix it in the 0.21-fixes
 branch, or close it with a note that this is a discouraged, or untested
 configuration.
