Could be overheating. When Myth has problems with LiveTV but not recorded TV
it indicates that the extra load of recording as well as watching might be a
problem. Has it got worse in the last few months (i.e. since summer
started)?

Looks like 64bit pointers - it might be more stable running 32bits. Though I
think there are plenty of people using 64bits without issues these days.

CPU maxing out won't cause crashes, just skips and unwatchable video.
