When I was last home I did set up Jellyfin from my dad's PC (which is basically always on) and downloaded a few movies for them. But some of the movies had inconsistent subtitles or needed massaging. Or Jellyfin needed to take an extra moment to transcode the subtitle format for some reason. So if I were able to ensure that stuff is all sorted out, it works great. But if I'm not there it might get weird.
