Nice to have you here with us on Lemmy, Christian

Selfhosting an *arr stack with Plex/Jellyfin is the way.
There’s also Tdarr for automatic transcoding of videos right after they get downloaded, haven’t tried it yet so can’t comment.

There’s not nearly enough supers and dupers in your comment.
IIRC the_donald users tried to go there and quickly had to run away crying, they’ve got bullied hard.
