But that doesn't answer to the issue of settling with a schedule which
conflicts when there are also idle tuners.

19-23 are a single digital tuner with multirec.  24 and 25 are two
PVR-x50 tuners.

On Sept. 22, at 21:00 there are no recordings "in progress" (i.e. all
recordings prior to 21:00 end prior to 21:00) so all tuners are available.

Yes, those are the analog PVR-x50 tuners.

Right.  The digital multirecs of a single tuner.

Correct assumption.

No, virtual/multirec tuners on the same physical digital tuner.

Right.  Which it can do on a single digital tuner.

Right.  Person of Interest was a conflict and Whitney was being recorded
earlier.  That Person of Interest conflict is a good example of
something that could and should have been scheduled on one of the analog

There is indeed a 20 and 21 on the digital tuner.  At least that's what
mythweb's status page tells me.

No, not at all.  See above.

But there's no corner.  Analog tuners 24 and 25 were still available to
be schedule on.

What should I check specifically, given that the scheduler and recorder
can schedule and record from the multirec card the other 95% of the time.

That's what I followed when I reconfigured my tuners just recently.
