Abstract: A controller for use by a user is utilized to select media for playback by an entertainment system. A display displays a hierarchy of levels of options to the user. One level of the hierarchy of levels is displayed at a time. A physical dial is utilized to select an option on the one level of the hierarchy of levels in response to a physical movement of the physical dial. A processing device updates the display of the hierarchy of levels in response to selection of the option by the user.
