I think I have found a way to delete the deleted recordings using 
mythweb.  Using the Recorded Programs UI with the Show group = Deleted, 
I can still see all of the deleted recordings.  From there I can really 
delete them one by one using the Delete button.  I can only do a few at 
a time, though, otherwise mythweb fails with an error about too many 
connections.
