Honestly, thank you for posting the details and results. Regardless of anyone’s opinions, it’s a fascinating thought experiment.

Has Jellyfin improved its subtitle fetching?It’s been awhile since using Jellyfin. I stayed with Plex because downloading subtitles on the fly wasn’t available in Jellyfin, and no extensions for it either.

If you can’t do better, then at least add some cute cat pictures in it. At least then I’ll feel a crumb of joy with every wasted effort!
