I got these at first too

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.

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 :-
