Series recordings where no episode number is available from EPG source, fails to record more than one episode.

h4. Steps to Reproduce
Set a series recording of a program without episode information (e.g. "news").
Select in SetupTV.exe: Check Episodes of already recorded programs to prevent duplicate recordings of repeated broadcasts.
Select episode key=Episode number
Wait for second recording of series to start and notice that it fails to record, claiming that episode (..) has already been recorded.
