The picture-in-picture window is presented in conjunction with a navigation feature on the display. A two-dimensional input associated with the navigation feature is received from a remote control having a touchpad or other two-dimensional input device. The picture-in-picture window on the display is appropriately adjusted in response to the two-dimensional input.
