I don't have an ATI card in the system, just the one Nvidia card.
Hmm, okay, I'm in Windows now and a quick check shows that
pci1441,8800 (pci14f1 actually) is my Hauppauge WinTV card.
The location of the computer case makes me hesitant to undertake
the task of removing a card.
At first chance I'll have a go at it.
