Abstract: PROBLEM TO BE SOLVED: To automatically reproduce a specific video program stored in a digital video disk(DVD) with a movie by providing a step, etc., for automatically selecting one of plural prescribed video programs or movies at the time of starting displaying of the DVD. SOLUTION: The value of an argument stored in a DVD is read (S308). Next, Ndick being a numerical between 0 and Ntotal is calculated by a microprocessor with a microcode coefficient Nzero as a first track, with Ntotal as the total number of tracks and with Nvideo as the first track of a video (S310). Next, Rpick is calculated by using a prescribed expression (S311). Further, a reading head is sought with respect to a track decided as Nzero+Rpick (S312) to judge the completion propriety of the reproduction of an Nzero+Rpick track (S314). Then, when track reproduction is already completed, the reading head is moved to an Nvideo track (S316) to reproduce read picture data (S318).
