When you display the TV Viewing Status screen, it will display channels the tuners were recently tuned to. There is not a problem with the Hopper and Joey if it shows 2 tuners in use even though you may only have 1 TV on. As soon as another tuner is used, it will display on the TV Viewing Status screen. Are you only having problems saving your NBC channel to your Favorites Lists? What software version is your Hopper and Joey? Please let me know. Thanks.
