You could delete them and allow re-record.... of course that would
delete them unless you exported them to videos first.

You could, fairly easily, delete the entries from your "oldrecorded"
table for those shows you want to re-record.  I am pretty sure this
won't disrupt the current recordings on the disk.  Of course, then you
will have duplicates when the show re-records.

You could probably write a script to loop through every file in your
recordings, deleting the related entry in the "oldrecorded" table.

You might also be able to create another script that would run user
job after recording is complete that would search for the new
recording's programid (and/or subtitle and description) in the
"recorded" table, and if it finds two of the same, it deletes the old
one; so then you would only have a single copy of the recording.
