Oh, and I can't tell from the information you've provided, but it is 
possible that you still have a copy of that episode in your system (it's 
not yet deleted nor expired).  If that's the case, someone has selected 
the episode and set "Allow this episode to re-record."  Or, it's 
possible that the episode was recorded and the backend detected 
sufficient corruption of the recording that it deemed the recording to 
have failed, so it marked it to allow re-record.
