This is, to the best of my memory, the first time someone on this list
has actually discussed a good reason to use:

Time to record before start of show (in seconds)
This global setting allows the recorder to start before the scheduled
start time. It does not affect the scheduler. It is ignored when two
shows have been scheduled without enough time in between.

That's pretty much exactly what it's designed to do--start the recording
early if it's the capture card is not already in use.  The external
channel change script then takes care of whatever needs to be
done--sending the discreet power-on command, waiting 45 seconds for the
box to boot--just in case--then changing the channel as appropriate, etc.

Nah.  If you didn't use the above, it would just prevent the "whatever"
that would have been recording from recording because it conflicted with
the following show.  ;)
