If the series is old enough, it may already have been expired from
MythTV's memory.  Check in Manage Recordings > Previously Recorded to
see if there are still episodes listed there.  Remember that when
finding things in any mythfrontend list screen, you can use Ctrl-S to
bring up a search box.

I am not sure exactly how it works, but there is a limit to how long
old recordings will show up in the Previously Recorded list.  However,
the corresponding database table (oldrecorded) has much older
recordings.  In my database, I have 2016-11-06 as the oldest recording
in Previously Recorded.  In oldrecorded, the oldest recording is
2009-11-10.  If a recording is in Previously Recorded, from there you
can hit Enter to get these options:

Allow this episode to re-record
Remove this episode from the list
Remove all episodes for this title

The latter option being the one you want.  But if the recording is so
old that it does not show up in the Previously Recorded list, then I
think you will need to remove the entries from the oldrecorded table
manually, and as with all direct database manipulations, that is
hazardous without knowing exactly what you are doing.  There may now
be a Services API call that you can use that will remove things from
oldrecorded.  That would be a safe way to do it.  And there may also
be options via the Python or Perl bindings.
