A playback device comprising: a command input unit to accept a command entered by the user; a display controller to generate image data on a manipulating-function menu screen including an array of a plurality of identification miniature images for respective ones of a plurality of to-be-replayed objects each comprising a content; and a display output unit to output the manipulating-function menu screen image data from the display controller to a display unit, the display controller functioning to display a first manipulating-function menu screen in which the array of the plurality of identification miniature images for the respective ones of the plurality of to-be-replayed objects is displayed on a one-sided position on one display screen, wherein one of the to-be-replayed objects corresponding to one of the identification miniature images in a predetermined position is a to-be-replayed object of interest, and a second manipulating-function menu screen in which the array of the plurality of identification miniature images for respective ones of the plurality of to-be-replayed objects is displayed on another one-sided position on one display screen, wherein the one of the to-be-replayed objects corresponding to the one of the identification miniature images in the predetermined position is the to-be-replayed object of interest, characterized in that the display controller functions to selectively display, by a predetermined operation made via the command input unit, the first and the second manipulating-function menu screens, wherein a first group of a plurality of manipulating-function items for the to-be-replayed object of interest is displayed in the first manipulating-function menu screen so that one of the manipulating-function items can be selected by an operation made via the command input unit, and with an indication of which one of the manipulating-function items is being selected, wherein a second group of a plurality of manipulating-function items for the entire array of the plurality of identification miniature images for all of the plurality of to-be-replayed objects, is displayed in the second manipulating-function menu screen so that one of the manipulating-function items can be selected by an operation made via the command input unit, and with an indication of which one of the manipulating-function items is being selected; the display controller further functioning to display, during selection of any one of the manipulating-function items included in at least the first group, the identification miniature image corresponding to the to-be-replayed object of interest in a different way from the other identification images. a command input unit to accept a command entered by the user;
