Thanks for you concern, though. At my place OTA is just not possible. Or at least I could never get it to have a usable signal. I can confirm the above method of adding channels works, however, as I'm now in front of the frontend/backend system and am seeing HD-CBS live and clear! Now to just finish adding the other channels manually, and setting up the appropriate xmltv ids to get them some usable guide info!
