Good day! I am trying to find a good alternative as not to use the"smart" functions or using an Xbox to consume our media. I found a few options ie like plasma big screen but it’s no longer in development. Essentially I would line love to have it running on an rpi4 and just hooked up to the TV.
As others have suggested, OSMC is OK, but personally I prefer having Android so that I can use SmarttubeNext and access native apps for stuff like Jellyfin, Dropout, Nebula, etc. For years I played with various Linux options, but in the end I ditched it all for an Nvidia Shield and I couldn’t be happier with the results.
