I installed it in a Windows Vista Ultimate x64 machine with Intel Q6600 quad processor and 8 GB of memory. I have it hooked up to Comcast digital cable. It will detect analog channels, but not digital ones in the Catalyst Media Center. Windows Media Center detects the digital channels, but won't play them. I just get snow. Can someone help me with this?
TV Tuner cards will only pick up channels from your cable company that are sent "in the clear", meaning unscrambled. I just recently upgraded to get the HD channels Comcast delivers, so I can try it on my own system when I get home, but I wouldn't expect to see anything.
I've run into the same problem and even more frustrating ATI does not support there own product. You can't use the remote that came with it because it only works with Windows Media player and that won't pick up the digital channels. I figured I would try to hack my registry to make it work with the remote for Catalyst Media Center. I hope this has helped a little.
