i MAY have a fix for jellyfin's inept handling of DBZ...
had another jellyfin user post screenshots of their formatting and the result in jellyfin so in going to try that
HOLY SHIT IT FINALLY WORKED!
Apparently the absolute format is Showname>Season #>Showname (YEAR) - S##E## - Optional Episode Name.mkv
it apparently also works without separate season directories
Now i'll have to do Dragon Ball as well... although it doesn't play nice through jellyfin because RMVB is an odd format
this is mst3k
