While my 2 frontend systems have no problem at all, I've got a monitor
hooked up to my backend that I use occasionally for testing. I've
noticed a similar problem with it, where often when I exit playback,
it appears to lockup. But my screen doesn't go blank. It just keeps
displaying the last frame. What I discovered was that if I have
another window open (say, a terminal) and I alt-tab to that other
window, then it redraws the screen and everything is fine. I can
alt-tab back to myth and everything works fine.

The differences between this machine and my 2 frontends are very
minimal. All 3 systems use the same motherboard, CPU, ram, etc. Same
version of debian (though different packages installed) etc. The main
difference between these systems is that the dedicated frontends have
a G210 based graphics card using VDPAU and HDMI, whereas the backend
is just using the onboard nvidia 7150 graphics with myth's software
playback and VGA. A few years ago, before I added the G210 cards, my
frontends were also using the onboard video, and none of the systems
had the problem then. But then I was running with a different version
of debian, it was 32-bit, I had different drivers, an older version of
mythtv, etc, so a lot of things were different, and thus I'm not sure
which element was responsible for breaking things.
