One aspect I forgot to mention, and again, others can correct me if
I'm missing something:

In any cases where the rescan simply ends up changing the frequency of
an existing channel in your database, the existing XMLTV should be
unaffected. That's because that channel will already be assigned to
the proper xmltvid, which is all that's needed for your existing XMLTV
setup to work.
