The problem I had was more or less exactly as you described but worse. Watching live TV was fine but any hard disk or network activity caused glitches, both in the recording and on the live display. I tried all sorts of things to fix it, increased buffer sizes, upgraded drivers, messed with PCI latency settings, changed network cards, overclocked the CPU, etc etc. Nothing seemed to help much. It just seemed to be a PCI bandwidth problem and there was nothing I could do about it. Eventually I gave up and switched to a mainboard with a BX chipset. All the problems went away (until I added a second dvb card, but thats another story)
