Hi, Just for the record, I can confirm that the mainboard/chipset may be the most important factor...
On my previous board (Asus P4P800), I could not even enable HT with my PVR-350's in the system or it would lock up within 8 ~ 10 hours. My current board (MSI with Intel 945 chipset) has no problem at all, doing software RAID5 on a Promise 20269 and RAID1 on the internal SATA (ICH7) controllers.
