Summary:
A method wherein contents of DVDs may be restricted based upon purchased certificates is provided. The certificates allow for secured information on playback. Specifically, whenever a DVD is to be played, a certificate is consulted to determine whether the content of the DVD should be played with or without commercial interruptions. If the certificates provide for commercial interruptions, then commercials can be obtained from an online service that renders commercials on demand, or from the DVD itself. In such a case, the content of the DVD may be interspersed with commercials.
