Zusammenfassung:The possibility of one DVD spawning countless perfect digital copies is, for the movie industry, the scenario for the ultimate horror show. Following the breaking of the content scramble encryption system for DVDs by a 16-year-old Norwegian programmer, Jon Johanssen, and the following lawsuit (decided in favour of the movie industry), several approaches for preventing the copying of DVDs are being considered.
