I am using a SiS. I havent heard of an issues with this chipset 2. You could try maxing out buffers by adding this: "options ivtv > enc_mpg_buffers=16" to /etc/modprobe.conf or your equivalent.

I have tried to move my cards around my between my firewire, pvr, usb, sound card, video card there is always overlap with something. Do you guys think this is a hardware issue or a software issue? If i could just get a new MB and not mess with all the "shoting in the dark" fixes I would just do that. Thanks, Mitchell
