Scanning for digital channels (2 Viewers)

[Navigatr85]

Hi, I recently installed MediaPortal, and I'm having trouble getting it to detect digital channels. I have a hybrid TV tuner card that does NTSC, ATSC, and QAM. MediaPortal seems to have correctly detected the two tuners on the card. I opened up the "TV-server configuration", selected the analog tuner, and clicked "Scan for channels", and it detected a bunch of channels. But then when I selected the ATSC tuner and did a scan for channels, it didn't detect anything. I chose "Tune QAM" because that's what cable TV uses. Isn't that right? I wasn't sure what to select under "QAM tuning frequencies", so I just left it at the first one, "QAM HRC+3". Should I just try doing a scan with every option in that list, one by one? I'd rather not do that, because every time I do a scan, it takes two or three hours. Some further details that might help:

TV tuner card: Hauppauge WinTV-HVR 1800
Cable Provider: Comcast
Location: near Wilmington, DE
