Editing DVDs - How Far is Too Far?

Modern technology has allowed for editing of movies on DVD without the consent of studios. One service called CleanFlicks distributes edited versions of films, while another, CleanPlay, sells software that allows parents to filter out content they don't want their kids to see. Attorney Carrie Beyer, who wrote about the subject for the University of Illinois Law Review, tells AM 580's Jeff Bossert that both services have become the subject of legal battles over who has the right to remove or alter a film's content.
