"While many people many consider it trivial, the cracking of the DVD encryption format is a very major event. The encryption capabilities were one of the main reasons why DVD drives and disks took so long to be released. But, as in all things, many things can be learned from this. One of the major lessons is that of security."
"Bad security is easy to implement, with a major example of it being the DVD encryption. By pairing relatively weak encryption with a fixed set of decryption keys, it becomes easier to break, and harder to prevent someone who has already broken one to break others, and thus makes cycling the decode keys almost pointless."
