What formats can your TV receive wirelessly, is it the MKV or MP4 open the manual, are you connected with a wire or wireless. Come on girl it takes time to get this crap down, gota learn this shit, or you will be stuck to cable all your life. You also have to allow it though all of your antivirus programs, and your firewall program, yea its hell and a pain but we all have to deal with it.
