Maybe the problem is in the software, not the hardware. What happens
if you just run the machine for a few weeks without MythTV running.
Or you could run top or  something occasionally and see if there is a
memory leak or maybe try the windows solution and manually reboot it
every evening and see if the problem goes away. Or perhaps there is a
better way to narrow down the problem.
