I think I'm right in saying it should be impossible for a user space 
program like MythTV to crash the kernel so it's most likely either a 
kernel or driver bug. In this case the video drivers are the most likely 

It's not clear when you say a hard crash what exactly you see. Does the 
box just shutdown completely with no lights, fans or any sign of life? I 
so a very common possibility with these small boxes with external bricks 
for the power supply is a failing power supply that falls over when 
asked to provide to much power like when playing videos or doing some 
CPU intensive task like comm-flagging. Definitely worth trying another 
power supply if you have one handy even if it just eliminates one 
possible cause.
