twin card problems in media center

I have a nice ATI 650 pro PCI that I just bought dual tuner, just have regular cable on the analog and my antenna on the digital for OTA HD broadcasts. Anyways I can never get the thing to broadcast anything off of my antenna (digital) signal in media center. It only sees my analog channels. I also tried using this with other software made by intervideo and actually got the channels to show up in a list but when I bought them up the entire thing crashed. And whats with this Catalyst Media Center program that comes with the card, it won't even install on my x64 ultimate, is there no compatable 64bit version of that software? I couldn't find any. This is my first time owning a tv tuner and so far it's not been a good experience. I just wanted to record some of my HDTV late night shows while I am sleeping. I also tried mediaportal but haven't had any luck getting it to work at all with my card.

Thank you, those instructions look great can't wait to try.

I had the same issue with my ATI card so I bought a Hauppauge WinTV-HVR 1800 and I'm very happy with it. It worked right the 1st time right outta the box.
