I would understand if atscscan was showing channel "names" of the form
[xxxx], but they are mostly the actual ASCII-character channel names
(like KTVU-DT and such).

The other piece of information is that I am using an antenna for OTA
scan and not QAM.

It is a real pain because, mythfilldatabase can't find any data for the
channel numbers that mythtv-setup found.

It's up to you to cast it into a void or not.
