An improved audio-visual playback system which identifies and displays only high-interest segments of a program, according to peaks or thresholds of positive and negative user interaction events from a multitude of other users of the program. A personal video recorder which receives a history of positive user interaction events such as "thumbs up" approval events, jump backward events, and rewind events, and negative user interaction events such as "thumbs down" disapproval events, jump forward events, and fast forward events. If prior viewers gave high interest approval for a segment, either by affirmatively voting "thumbs up" or by rewatching the segment, the playback system plays that segment; otherwise the segment is skipped or muted, such that user can watch only the "highlights".
