I have a recently built HTPC running Windows 7 32-bit ultimate. I am attempting to record Clear QAM. I have two tuner cards in it: an ATI TV Wonder 650 (PCI) and a Hauppage WinTV-HVR-1600. Media Center detects the analog and digital tuners, but when I go to scan channels, I only end up with analog channels. If I try to add the QAM channels by entering the number, it won't bring anything up. I cannot figure out what is wrong. There are definitely ClearQAM channels to record. My TV can see quite a few of them. I looked around with google, but everything seem to say it should find the digital channels on its own. How do I use my digital tuners?
