Repeating during mastering

Sometimes, at either the beginning, middle and/or even the end of a videotape, a portion of the master tape is repeated. This likely occurs due to an error where the employee(s) at the duplication facility accidentally press the repeat button on their master tape system and do not realize what the repeat button does until he/she/they press(es) it again. It is probably one of the super rarest.
