Future airings of the same series/season/episode should not be scheduled for recorded automatically if Plex already recorded it successfully using the same “Record Series” task that. Example: Record New & Reruns of PawPatrol. Plex records S2E4 from a TV tuner, transcodes it, and saves it to the library successfully. Three weeks later S2E4 shows up again in the EPG but Plex now knows not to schedule a recording of S2E4 because it has already been done successfully… thereby freeing up the TV turner for something else.
