Skipping during mastering

Sometimes, at either the beginning, the middle and/or even the end of a videotape, either one or a few second(s) of the master tape is/are skipped. It is not known why this occurs. Probably another one of the super rarest.

Known incidents

 * 50 Classic All-Star Cartoons Vol. 1 (Burbank Video, 1991) - On several pressings, a few seconds of the credits to the short subject Japoteurs are skipped.
