[mythtv-users] Remote Frontend HD playback causes Segfault

I can't for the life of me figure this one out. I'm running F7 on both
my backend and frontend. My backend (though its the lesser power
machine) plays back HD content just fine. But my beefier frontend
segfaults within the first 30 seconds of playback. It seems to vary,
sometimes I get the segfault immediately, sometimes I think its finally
going to work then boom.
I need some guidance on what to try, I've changed interlacing, with and
without opengl timing, even tried XvMC thought this machine shouldn't
need it. I've tried several nvidia drivers (currently using 100.14.11).
I don't think its a driver issue because X is not crashing, just
mythfrontend is crashing. Also playback of SD stuff works fine,
mythfrontend can run for days perhaps for eternity as long as I don't
try to play back an HD clip.
Currently running ATrpms-bleeding SVN revision 13756. I suppose I could
try building from source and enabling the debug stuff. But I was hoping
someone had a few hints before I went through that.
I do have one clue, earlier I believe artsd was using /dev/dsp for
whatever reason so when I tried to play an HD clip I got an message
saying it was disabling audio. Well, the clip played fine after that,
except the obvious no sound, but at least it didn't segfault. So.....
I'm tinkering with the audio buffering options.
