In theory, you need to either enable opengl vsync in mythtv or opengl
sync to vblank in nvidia settings. Enabling both shouldn't do any

In reality, I've found I get tearing if I don't enable opengl sync to
vblank in nvidia settings and enabling both results in a small
performance/frame rate hit that means I get a small glitch in playback
every 20 seconds or so.

So I suggest you try enabling opengl sync to vblank (if you haven't
done so already) - though the best setup is likely to be
hardware/driver dependant.



(P.S. I take it you're not seeing any more crashes with the patch applied?)
