Save yourself the pain and suffering of input lag, dropped connections, battery swapping, and start up time (as the wireless device pops out of standby), and just get yourself a good ole usb extension cable and repeater. This goes double or triple if you intend to play any games at all on the TV. For just clicking on an mkv file, a wireless device will do you. But it will do you poorly.
