Having done an ATSC scan at a friend's house a couple of weeks ago, Myth
scans ATSC channels starting with channel 2 by default.

I also had to re-scan recently as one of my ATSC channels switched from VHF
channel 7 to UHF channel 42 - and since I don't watch commercials, I didn't
know that it had moved until I had a handful of "WHDH has moved to channel
42 - please re-scan your converter box".
