Hi all. I have been a happy MythTV user for roughly 3 years now, and have loved it. I've recently upgraded my entire mythtv setup to an HD setup, and have begun to notice that my mythtv box crashes from time to time during recordings. And when say crash, I mean hard-crash: no network, keyboard control, display output, nothing. I am never able to see any type of error on the screen (probably from X blanking the screen). Anyways, because I don't want to spend a ton of money replacing each bit of hardware until something works, I'll list out as many facts as I can here. I'm hoping for someone here to be able to help me figure this one out.

My wife gets very upset when her soap-operas don't record, and with the new fall-season shows coming up (Heroes!), I'd hate to miss any of those either :-) Thanks!
