EDIT: DIRECTV said a re-download of the local channel database (Re-run Initial Off Air Setup) is the only fix as the station and not DIRECTV supplies the physical channel number. I ran the setup and the problem was corrected. I am now getting a better signal on 6-1 (100%) than 20-1 (96%).
For whatever reason, your HR20 may have needed to be forced to refresh its local channel mapping (not particularly surprising), but you were not given accurate information from the DirecTV CSR (also, not particularly surprising), as that info most definately comes from the DirecTV satellite stream, and is supposed
to update in real-time. But, as you saw, doesn't always.
Both of my HR20s moved their mapping of 26-1 and 38-1 from physical frequency 50 to frequency 15 without me having to re-run anything or reboot. One of my HR20s moved 6-1 to physical 43 (from 21) within hours after channel 6 moved without me having to do anything. The other one failed to do so, and still failed to do so after a reboot, days later. I'll check and see if its moved today, and if not, I'll try re-running the set up on it.
