How do you shut off the Revue? If I turn off the TV and then turn it on, the Revue homepage is displayed. In the upper right hand corner of the keyboard are three buttons, AVR, STB and TV. When I press the first two, nothing happens. When I press the TV button, the TV shuts off. Is the Revue supposed to be always on? Right now, there is one green button displayed on the Revue Box. To shut it off, I unplug it from the wall.
