A reproducing apparatus performing reproduction of a play list by
inserting a frozen image when the length of data of a clip to be referred
by the play list is smaller than the minimum unit which is capable of
continuing reproduction of video/audio (Continuous Data Area (CDA)), or
by combining the clip equal to or smaller than the CDA with part of
another clip to be referred by the play list to generate a new combined
clip having a length equal to or longer than the CDA, and changing a
reference clip in the play list into the combined clip.
