The MPAA (Motion Picture Association of America), along with a number of studios have sued software company RealNetworks over its RealDVD software, which allows consumers to make copies of DVDs they own. The RealDVD does however, encrypt the copies it makes, with the intent of preventing file sharing (as well as conforming to Hollywood rules on DVD protection). The music industry has somewhat wised up as of late that consumers of digital music value the usability of the media they purchase. Because of that you can now purchase songs with little worry they will come packaged with restrictive DRM (digital rights management). With this move, it would appear that the movie industry is less concerned with providing that kind of flexibility to the consumer.
