I've got an Xbox 360 and a Vista Media Center in my TV room and bought an Xbox 360 Universal Media Remote. The problem I've got is that both my media center and the Xbox receive the signals from the remote, so if I hit "Power" both turn off, "Play" and they both start to play etc. Is there a way to force one of the devices to ignore the remote? Or am I better off just forking over the dough for a Harmony universal remote? TIA.
