When I first installed Vista it did not recognize the ATI TV Wonder Pro card. I installed these by installing from a list, and choosing ATI under TV Tuners. It has the card listed so I installed the embedded driver. The ATI Wonder Pro software, including MMC 9.15 didn't work, even after successfully installing it. I managed to run the MMC once and got thru the initialization, but I never got sound or picture (I use Composite since I have Satellite TV). Windows Media Center doesn't recognize the hardware either. I decided to try something outside the box - so I uninstalled all the ATI software (left the driver for the capture card installed) then installed the drivers for the TV Wonder Elite. You have to use XP compatibility for this or it won't work. I downloaded and installed Cyberlinks PowerCinema (http://www.cyberlink.com/multi/download/trials_12_ENU.html). Make sure to use compat mode for XP again. This worked great after a trip to settings. As usual, the installation insists on either Cable or Antenna, which I don't use; this is irritating, but I was able to get it working. After this is installed, you have to change the program's compatibility to Windows XP so it won't lock up on you. After that, it worked perfectly and I haven't had any trouble with it.
