multible graphics cards vista disables secondary card

Hi, issues I've been experiencing with Vista, I currently have an ATI 9600 Pro 128mb adapter and an ATI 7500 64mb card on my PC, but whenever I go into Vista the card that isn't set as the primary card in BIOS is deactivatd. Its being reported as not having the appropriate drivers. To confirm the issue I went into BIOS and changed the primary adapter from PCI (ATI 7500) to AGP (ATI 9600 Pro) and it then did the same only this time disabling the PCI (ATI 7500) slot.
Does anyone know how to get around this issue, could it be a driver issue.
Part 2
Whenever I try using Live TV in Media Center I get constant studdering (Picture and sound)
Any Input would be appreciated.

I have dual nVidia cards running fine in Vista and all monitors work. When first loaded, Vista wasn't using the monitors on the secondary card until I went into Display Settings and clicked on the unused monitors and then checked the box to "Extend the desktop onto this monitor". Then they all worked fine.
I don't know with ATI, but when I updated the nVidia display drivers off there website it only updated the primary card. I then had to go into Device Manager and update the secondary card manually.
