An HDHomerun Prime isn't very much comparable with a DVR. I suppose some of that has to do with how many TVs you're trying to serve but I've yet to see a TV that has a built-in client and the DVR leaves a lot to be desired in addition to requiring the assistance of a media server.
Solutions based on tuners and media servers are rarely family friendly.
What do you come here to argue with everyone? The SD Dvr works fine It's easy, but for someone like you it might be to complicated
