Jellyfin is very versatile but a bit clunky. I have it set up for my parents on their Roku and it works well enough for them. I set it up for other family members on their WebOS TV but they don’t really use it. I used to use it with Roku as well, but had issues with some captions, Dolby Atmos and HDR. I finally broke down and got an Nvidia shield, which fixed all my problems since the developers focus on Android TV the most. I also have Plex, and it is easier to set up, looks more polished, but is less versatile.
