It is perfectly fine to use the “year-seasons” like they are on TheTVDB.
/Series <-- this folder is added to the library
/Looney Tunes (1929) - {tvdb-72514}
/Season 1936
Looney Tunes - S1936E07 - Page Miss Glory.mkv
After adding the files and scanning the library, be sure to edit the series and set the Episode Ordering to “TheTVDB (Aired)”.
If there is a mismatch, unmatch the series first, then pick Match again and pick “Looney Tunes (1929)”.
This is working with the default “Plex Series” agent. No trickery with collections or custom agents necessary.
