I have a Nvidia shield pro currently running Plex and Jellyfin (sometimes Jellyfin cannot decode the videos and trans-coding is off), I am thinking about moving away from that and go custom Linux build on a mini PC. For live TV I have the app from my internet provider, although I rarely use it. Because the shield runs AndroidTV you can basically just install Prime, Disney, Netflix, etc. apps to run those. For YouTube I use a modified app that has ad and sponsor block build in, can't remember which one it is, but there are enough to choose from. Everything is routed through a Pi-Hole with dns enforced on the router to use it, instead of external ones (in case an app gets smart and tries to use their own). Next to the Shield I also have an extensive DVD/Blue ray collection, most of which have been moved to the NAS that has the Jellyfin server. There are still enough things to do, but I don't have the time to do all the things I want to do.
