I’m trying to get the TV show “Undeclared” in the correct order.
The original DVD release was in the wrong order and so is the tvdb DVD order.
In Plex I can choose between aired, DVD and absolute episode ordering, they’re all wrong.
On theTVDB they have something called “Chronological Order” which would be the correct one. Undeclared - Chronological Order - Season 1 - TheTVDB.com
I can’t seem to find a way to have that in Plex
Unfortunately, the only solution (currently, using an online metadata database) is to order your files to match one of the orderings available in Plex (the ones you listed). I’m pretty sure there’s an existing feature request to support additional ordering options; I’ll link it here if I find it.
Another option would be to match this series to the personal media agent and manually add/enter its metadata.
[Edit]
This is the feature suggestion I was thinking of:
