Sorry I can't be more help right now, but it CAN be done - keep looking.
That's one of the downsides to WatchOn... The menus aren't very cohesive and finding the right place to go to change or add settings is tricky. Still a way cool app.
I just walked into our lunch room where the remote is usually slathered in pizza grease and setup the TV and local cable in about 30 seconds. Works perfect.
