If I plug my Comcast cable into the OTA IN on the 211, would the 211 see the digital free in the clean network locals? What about the SD analog stations? Reason I ask is that I was thinking about running a cable to that tuner and it's easier to run from an existing cable tv feed than my ota antenna feed on the other side of the house. I saw in the tuner menu and option for "cable TV" and IRC and HRC so it looks like this should be possible if it is enabled in the box. Thanks.
