Welp, we got Vista installed in the VM with no issues. It ran dog slow, even with all the pretty extras turned off. I bumped the VM’s memory from 1gig to 1.5gig and that helped a lot.
Anyways, I could not get the Hauppauge WinTV-PVR-USB2’s drivers to kick in. It kept saying something along the lines that the drivers were not made for this edition of windows.
Which is odd. I have been told that the NVTV drivers would not work and I have two Vista boxes running with nVidia NVTV dual tuner cards running great.
Welp, that’s that for the WinTV-PVR, we’re going to try out the Adaptec DUAL Tuner USB device for MCE. Gonna order one soon and give that a go. The more tuner’s the better

I am not certian how you managed to get the nvtv dual tuner to work properly in Vista. I could only get it to recive 1 signal not 2. If you have it recieving 2 signals there is a hell of alot of people that would like to know how you managed that, including myself
