Have you ever heard of that chromecast thing though joey?
They're fairly easy to use, its about the size of a watch. Its plugs into a HDMI socket on your TV and then it will connect to your wifi - you can play from youtube etc. Install cromecast app on your phone/tablet and you can stream onto you TV from it. Mobdro / showbox etc all work pretty well. MX Player sometimes gets in the way so may need to remove it if you have it installed. There is loads on the net about how to use it etc.
