I have a Mac book pro running windows 7 home premium 64 bit through boot camp. I have wintv-hvr 900 usb tuner. work okay on it's own program. I want to use media center live tv.

I install and  get all the channels etc. but when I try to use live tv it informs me "Files needed to display video are not installed or working properly. Restart windows media or the computer"

I purchased a new computer yesterday and it has windows 7 with media center. I installed the tuner on windows 7 media center and it works perfectly. I noticed how ever the set asked to set up the video screen " aspect ratio" and other questions about the set up. But this doesn't come up in the options on the mac.

Please could I get some easy to follow help as this is ery frustating. 

 Have you updated your video card drivers on your mbp with newer official nvidia drivers instead of the bootcamp ones?
