This is going to sound strange, but I don't own a TV, and haven't owned one for 25 years. But we are helping my mother-in-law move into a new apartment, and she has two Roku TVs, one for the living room and one for her bedroom, so I am trying to learn the ropes of setting them up. Unfortunately we are hitting a snag: sometimes when we try to use the remote control to operate the TV in that room, the one in the other room responds instead. Is there a way to pair a remote to a specific TV so that we can control just one TV at a time?
