Ok, I was getting confused between the reactivate the duplicate
field. Must have gotten lost tracing the menus.

The "allow re-record" button in the "Previous Recorded" menu clears
the duplicate flag in the old recorded table by calling ForgetHistory,
which makes the scheduler ignore that entry when joining for duplicates.

The thing is that this button appears on all current recordings, and
pressing this button seems to do SFA unless it's on an episode that is
currently on. Although I suppose that, once I delete the recording, it
will re-record then. Probably this button should be removed or made to
function correctly in these cases.

Any ideas on a means to allow a currently recorded program to
re-record without doing a delete? 

I tried using oldrecord.reactivate (as opposed to
oldrecstat.reactivate) in the scheduler, as well as adding a rerecord
flag to the recorded table. While I can get it to re-record, making it
stop after a single re-record is a bit more difficult.

I'm thinking now that if I can clear the duplicate flag in BOTH the
recorded and oldrecorded tables, it would do what I want. Should I
call ForgetHistory to deal with the oldrecorded table (since it does
some extra cleanup)? Conversly, should ForgetHistory clear the
duplicate flag in the recorded table. That should make the "allow
re-record" to work.
