LOL. I also record the first two, but record Corden instead of Kimmel.

So two of those three recordings cross midnight, and the third doesn't.
Are the recordings always 6 hours instead of one?  Are your recordings
set to start early/run late, or do they start/end on time? I.E. are the
recordings supposed to record for 60 minutes, or for 2+60+2 like mine.
If you have pre/post overrun, is that reflected in the overlong
recordings?  I.E. is the actual recording 6*60=360, or 2+(6*60)+2=364,
or 6*(2+60+2)=384. Just trying to find a pattern.

Not sure yet. Will let you know.

Can you try running 'mythbackend --printsched' on you backend system
and post the output. You don't have to stop the running backend. This
will run a second copy that dumps the scheduling info and then quits.
That might help figure out if the problem is in the scheduling of
recordings, or the act of recording. Feel free to mail directly to me
(mythtv @ love2code.net) if you don't want to post.
