OK, then on 3/13/2020 Virtual channel 2 moves from real channel 44 to 31.
Can I just go into MythWeb and change TB Channelinfo freqid for the four
sub channum's associated with channel 2 from 44 to a 31? Or do I need to do
a rescan on all the tuners?

Rescanning is a huge pain because the scan picks up the wrong station for
one of the channels and it is a pain to fake it out. I can't even remember
what I did.

I will also have another repack on 5/1/2020 for channels 7 and 11 so
whatever I need to do, I will need to do twice.
