Jellyfin is absolute dogshit though.

Sauce: I just installed it on my media server that concurrently runs plex. I run the app on a fire tv cube to use it... and it crashes* constantly.

Edit: More stuff :)

-My media library when imported immediately showed seasons of shows as separate shows, it doesn't intelligently automatically merge it like Plex would.

-Subtitle options are not consistent or robust. I MUST have subtitles due to having a multilingual family which is largely ESL, if they speak English at all. This is the problem I tried moving to jellyfin to fix.
