I am trying to install my ATI TV Wonder Elite TV tuner card on my XP Pro virtual machine - with no luck. My host OS is Vista Business which cannot run the bundled Power Cinema so I setup a virtual machine (VirtualBox) and installed XP Pro.
When I run the install CD to install the TV Tunder drivers I receive no errors, but when I open Power Cinema the option for TV is disabled. I also tried getting the XP drivers from ATI's website - same outcome
Open device manager on your Virtual XP box and look under display adapters. On my Virtual XP box (Server 2008 w/Hyper-V), it shows as "Microsoft Virtual Machine Bus Video Device" as opposed to the Geforce 8800GTS-640 that's installed. My guess (and it is just a guess) is that Power Cinema is not seeing a valid graphic device.
