If you add "--only-update-guide" to the mythfilldatabase command line,
that will prevent it from doing any channel updates or adds.  If you
are running mythfilldatabase internally from mythbackend, you may need
to turn that off and run it externally from systemd or a cron job in
order to add that option.
