I usually make backups of my movies for my nieces and nephews who handle things like any kid would, just give them a copy and let them break it, scratch it, without having to worry about replacing it with another original (read: spending another $20), all they have to do is insert it and hit play, I also like to cut the logos as well as the movie credits and any other previews and the preferred container that I use is ISO since my dvd players can play that and not avis. I guess this requisite only applies to people who are in the same boat.
