A movie stream recorded on a recording medium with accompanying management information according to a predetermined standard format is edited while satisfying an upper limit condition. When the number of play items or the number of playlist marks in a playlist has reached or approached the upper limit condition, last chapter information in the playlist is moved to the beginning of a subsequent playlist or a newly created playlist. Furthermore, in a case where there exists a margin against the upper limit condition regarding the number of play items or the number of playlist marks as one playlist even if contents of two or more adjacent playlists are combined, the playlists are integrated to reduce the number of playlists on the recording medium.
