I just replied to a thread from James Abernathy with the subject "USA
OTA FCC frequency rescan?" that you may want to check out. As far as I
know, the biggest pitfall of the channel rescan in mythtv-setup is the
possibility of new channels getting created when you really want to
just change the frequency of existing channels. This (also as far as I
know) is caused by the station changing the callsign that gets
reported from the signal itself.
Assuming you have something that can be used to just scan channels to
a file as I describe in that reply, you should be able to use the
channel editor to change and callsigns to the new ones before doing
the rescan to prevent that.
I'm actually one of those who's written utilities of my own to
manually change frequencies surgically, but again, I believe those
callsign changes are the main source of unwanted results.
