The movie industry is suing to block software that allows consumers to make copies of their DVDs. “The powerful Motion Picture Association of America argues that this type of software circumvents the anti-copying digital ‘locks’ that studios employ on DVDs, which would be illegal under the 1998 copyright law. There are typically no such locks on music CDs. The Motion Picture Association maintains that consumers aren’t permitted to make personal backups of DVDs, saying a movie buff whose disc becomes scratched needs to buy a new one.”
