Yes, the recordid is known.  Yes, rsOverlap could be a problem, as
could any kind of recurring recording.

The main problem is that the frontend doesn't talk directly to the
scheduler in the master backend about these things.  Instead,
everything goes through the database.  Consequently, the scheduler
can't tell the difference between the user wanting to uncancel a
recording and any other event which could cause a recshedule.

What I think we would probably need as a start is a new protocol
message to tell the master server to uncancel a recording.  There
would still be issues with recurring recordings.  For example, the
scheduler might have already decided on a later showing.
