Just got a Roamio plus and it's in the same cabinet as an S3. I want to change the remote address on the Roamio and I'm guessing it should be the same process as previous Tivos (go to system info screen, scroll to remote address, press Pause & Tivo - steady light - point at tivo and press "1" (or whatever number you choose). The number does not change on the screen - it stays at zero. Anyone know the correct process? Thanks.
