FWIW, it sounds more like X--or your system itself--locked up, and not 
that MythTV playback froze.  Generally, when this happens, it's due to 
problems with drivers (here, likely the display/graphics driver), and 
requires some sort of restart (at minimum X, but, IMHO, it's easier to 
reboot the system and know it will work than to try restarting different 
things over and over until it appears to work again).
