Don't know if this has been posted, but the HR20 now SCANS FOR OTA CHANNELS. I know this is not a documented feature, but I discovered this by accident. I have an antenna rotator and live in a place that I can get 3 markets. I cleared all saved OTA info, and set up my primary as Lansing, MI, and secondary as Flint, MI. My antenna was pointed to the Detroit market, and when the OTA set up was complete, only the Detroit stations were set up. The set up completely ignored the other 2 market's stations even though I put in their zip codes.
