Okay, I think I have this figured out. I do not know if this is the
optimal solution, but it worked.
First I used mythtv-setup -> Edit Channels and deleted all channels from
Video Source 'SD'. Then I re-scanned.
I noticed that when that was done I had a lot of new unwanted channels
so I marked them invisible. I also noticed that my channel that moved
overnight now had the changed freq. from 11 to 9 which is correct.
However the XMLTV ID was now blank.
So I ran as user 'mythtv':
tv_grab_zz_sdjson_sqlite --manage-lineups --config-file
Then did option 5 to manually select the channels. That exercise was
mostly to confirm what I already had.
When I exited, I did mythfilldatabase, then exited user mythtv and back
in mythtv-setup I found my changed channel had the XMLTV ID.
Next I started mythbackend up and everything is now work.
I have no idea what the right steps are but this worked for me.
