Thanks a lot. Before posting I actually tried removing sound cards, my other tuner card and my dxr3 -- still same problem. I also moved the card to a different slot and still same problem.

I didn't check the IRQ, though. I think I will try that and also go back to ivtv 0.1.9 as suggested by others.
