That would tend to indicate that you didn't properly delete all video
sources (or you somehow added channels before running
mythfilldatabase).  The delete all would have cleared everything out so
mfdb would have been allowed to do all the channel updates as inserts
(since there were no channels to update).

"Does not match" means you used a "timeslot" record rule and the
schedule has changed (which could be due to a channel-mapping issue as

This will happen if you have mostly "this channel" recording rules and
you change the callsigns of your channels (which is why you should
probably have mostly "any channel" rules).

It can also happen if you have 2 copies of channels in the DB (which can
also prevent recordings from occurring correctly despite what "Upcoming
Recordings" says).  If that's the case, going back to the "Delete all
video sources" approach and reconfiguring should fix it (but it's
critical that you reconfigure correctly so you don't get the same
"broken" configuration afterwards).
