It worked at some time.  It's possible it got broken somewhere along
the line.

How are you creating recrule?  The strongly preferred way to do so is
to call Dvr/GetRecordSchedule first.  That will give you a known, good
rule from which you can modify as needed.

There are 4 ways to call Dvr/GetRecordSchedule:

nRecordId > 0 : Return the existing recording rule itself.  Not
necessarily tied to a specific program.

!sTemplate.isEmpty() : Return the existing, template rule itself.

nRecordedId > 0 : Return the rule for the given recording.

nChanId > 0 && dStartTime.isValid() : Return the matching rule for the
given program.  Optionally, return an override rule when bMakeOverride
is set.
