I had left the patch for the owner of the ticket to merge into a testing
branch.  I think that person has left the project in pursuit of other
opportunities -- like a normal life ;)

 I am not sure why we have this behavior. Initially I thought that somebody

> It is a mistake.  At the end of the LiveTV recording, the database gets
updated by chanid and starttime, so both get thrown into the LiveTV group
if it is a scheduled recording and this is not a record from LiveTV (as in
they hit the record button while watching TV).  IIRC, there are three cases
where this can happen and similar code exists in each of the three cases.
 The case around line ~4503 is the one that produces the unintended
behavior.
