I recently signed up for a comcast bundle that includes my phone, internet, and 71 comcast cable channels. Here is my question- Is it possible to hook my comcast cable into my DISH 622 receiver and view the channels like I can with my OTA antenna? I have hooked the cable up and done a channel scan using the Cable, HRC, and IRC settings under "HDTV Setup" and it doesn't recognize any of the channels. Any information would be greatly appreciated. Thanks
