An audio and video disc reproducing apparatus

A system (41) for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk (23). The optical disk (23) has encoded on it a mixing master music and effects ("M&E") track, or a switching master M&E track. Individual audio tracks are provided for language-specific versions of the same motion picture, but these tracks have data recorded in them only where there is dialog.
