DVD Duplication Information

An 'easter egg' is a hidden segment that program writers or dvd creator hide withing the menu. It might be an outtake, some special interview, or just a joke. Lately, so-called easter eggs have been planted and publicized by the dvd maker.

Here's one site where I find many easter eggs on dvd's regularly. Be sure you are looking for the right region version.
