Yes, the AddHistory should also be qualified by 

   nextRecording->recstartts <= schedTime

I would have made the same mistake.

Yes, only to get accurate status.  Previously, the scheduler kept a
day's worth of state in memory for past recordings.  That worked fine
as long as the scheduler stayed up.  If the master backend crash or
was restarted, however, all of that state was lost and the EPG would
display things as if they had never been scheduled.
