Is your backend also running mysql? If so, and the errors are occurring 
on the half hour, it's likely the scheduling queries that are causing 
the error. I have 2 PVR-250's, 1 PVR-150, and an HDHR with one HD and 
one QAM/SD tuner setup, and I can record from all 5 at once with only 
very occasionally getting a buffer problem (which does not take down the 
whole box, btw), but I have the database on another machine, and I am 
running a RAID5 disk, so it can be done.
