If you use plain playlist structure (no playlist tree) and all episodes have the same title format (filename or metadata title tag), then you just sort items by title and you can recognize them by their URI.
Code: Select all
Title --> Title /\ URI
-------------- -------------- --------------
Episode 01.avi Episode 01.avi file:///...
Episode 02.avi Episode 01.avi file:///...
Episode 01.avi Episode 02.avi file:///...
Episode 02.avi Episode 02.avi file:///...
