I have done similar except I abandoned my old database and started from scratch.

I got these at first too
(http://lists.mythtv.org/pipermail/mythtv-users/2018-September/397398.html).
Like you, I could find no channel with a missing channel number - it
was a fresh scan into a clean DB after all, you wouldnt expect the
channel / multiplex tables to be messed up.

Here is the advice I got from Mike Bibbings<mike.bibbings at gmail.com>,
it has eliminated the messages completely, note the timeout settings
are in reference to the WinTVQuadHD card and would not necessarily
apply to your hardware :-

Maybe this would help you too.
-- Andy Thanks Andy I have made these changes and its halved the logs, 
in that its trying to tune only on one card now, but still channel .! 
Anyone any other ideas I can try? I don't think its actually causing a 
problem so maybe its just one of those weirdnesses I'll live with :) 
cheers Al
