It's a fairly common problem, most VIA-based boards won't even boot with 
PVR-500. It's not strictly a chipset problem, at least one vendor (ASUS) 
acknowleged the problem and released a BIOS update which fixes it. As far as 
I know, Soyo did not, I could not get Soyo Dragon 2 to boot with PVR-500.

Try the latest BIOS for your board, but if that does not work, you're pretty 
much hosed.


Also, with the .3x release of ivtv, it seems that the no_black_magic flag is
