If you are running something later than 0.18.1 there is a checkbox to  
disable OpenGL V-Sync support, or so I hear, I'm running 0.18.1.

I wound up just commenting out "load glx" in my /etc/X11/xorg.conf  
file, that solved it for me but others have apparently had different  
experiences.

You could also re-compile mythtv without OpenGL support but that's a  
bit drastic with most distributions (it's easy with Gentoo).

There are inconsistent reports about nVidia drivers, especially 8178  
it seems. One difference might be the fact that I'm using the 64-bit  
version, which may be behaving differently from the 32-bit ones.  
Regressing to older driver versions seem to have helped some folks  
but I couldn't get a clean compilation of any older driver module on  
a recent kernel.

You didn't mention your distribution so I don't know what  
"bitedness" (is that a word?) of driver you're using. I'm running  
Gentoo 2.6.15 on an amd64 in 64-bit mode.

Sure hope this all gets straightened out sooner or later.
