Record/playback device and related computer program

Abstract

A disk device provided in a record/playback device stores a plurality of programs as well as a record-setting content and playback history of each program. When specified by a remote controller as to a program to be played from a program list displayed on a television screen, a serial judging unit judges whether the specified program is an episode in a serial having another episode that was recorded prior to the specified program, by comparing the record-setting content of each of the programs. If judged in the affirmative, a playback judging unit judges whether the other episode has yet to be played, by referring to the playback history of the other episode. If judged in the affirmative, a presentation unit has displayed on the television screen that there is an unplayed episode in the serial. Then, when instructed by a user to start the playback from the unplayed episode, a playback unit plays the unplayed episode.
