Press the Home button. The Hopper 3 automatically tracks what you watch and puts tiles for the current and next shows for your most frequently watched channels on the Home screen. Highlight one of the tiles and press the Play button on the remote to immediately change to that channel. At least that is the way it works on my Wally, which has similar software to the Hopper series.
Thanks. I didn't see that when I was looking around. Not exactly the same as AT&T, but not too bad.
Guess I need to read over some of the old threads and just play around with everything on the remote, etc...
