NTP was set up on both machines, but had stopped on the backend in
question. That issue has been solved. However, given clock drift, it's
a little disturbing that a single second of clock offset could
actually cause a program to cancel recording.

Agreed. It's normal, easy to spot, and increases the "hands on" factor
of something that is supposed to make my life, and those who watch TV
in my household, easier. While the overlap not recording may make
sense in programming terms, it makes ZERO sense from a "human" factor.

No, I essentially have a problem with a very literal program doing
exactly what the scheduler is telling it to do, NOT what I told it to
do, which was to record both programs. Some sort of configurable fudge
factor would allow the backends to make more efficient use of the
