If you’re not wanting Remux Rips I’d really suggest converting your files to H.265, it’s got much better compression ratios than H.264. You can set up tdarr or fileflows (fileflows is much easier if you don’t want to write the ffmpeg yourself) to run through your library and automatically run conversions on new files. I use it to also strip foreign language tracks from files where it’s neither the primary track nor original language

Like most people here I bought a lifetime pass years ago and Plex just works (it passes the Wife Acceptance Test).

However, I am planning on spinning up Jellyfin and giving it a go and seeing what it’s like. I’m a bit nervous reading and things like multiple versions of the same movie displaying separately but I also think I saw a plugin that fixes that.
