Hello. I have a Comcast high definition DVR box and two HD TV's. I am sharing the box in between the two TVs via HDMI cable and I'm wondering how to change the box from the other room with the IR port. Is there wire that I can plug in in the back of the box, and brought it into the room where the second TV is so I can change the Channel on the remote? I'm sure there's something out there that can do this even a wireless option would be great but I don't mind hardwiring thanks again
