When i had my Logitech Review, i could control my Directv receiver and my Denon Amp over hdmi. I cant seem to do this with the Co-Star. I can control the Directv receiver via IR, and i can even control it using the android Google TV app, but only if the remote is pointed at the DTV box. I also tried using able remote and it wouldn't control the DTV box at all. Is the functionality not there with the Co-Star, or does it HAVE to communicate through the remote using IR?
