[mythtv-users] Locks up when spooling to ringbuffer...

I debugged a system similar to this for two weeks, RMAing and swapping 
out parts before I found out it was a faulty memory chip causing lockups 
during heavy load. Just a suggestion, and if you bought your memory off 
the cheapest listed vendor on pricewatch or from the "discount" bin at 
your local computer store I'd recommend replacing it anyways. I just 
fixed my friend's computer that had the EXACT same problem (he bought 
the same memory and motherboard).
