On my KT7A, geforce 2 pro, win98 box it kind of works now. It was locking up on me and I couldn't get it to work after moving around to a few open PCI slots and it still always locked. So the only way it works is go to Hauppage WinTV in your Programs menu, then select DIB DRAW. It works for me but the quality isn't too great. It jitters every now and then also.
I'm still experimenting to get this to work.
Oh it's sharing an IRQ with my SCSI card which it said might cause problems upon installation.
Anybody with a 'real' fix yet?
