AnyDVD is a device driver for Microsoft Windows which allows decryption of DVDs on the fly, as well as targeted removal of copy preventions and user operation prohibitions (UOPs). With an upgrade, it will also do the same for HD DVD and Blu-ray Disc. The AnyDVD program runs in the background, making discs unrestricted and region-free.
AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard (AES). Title keys are decrypted using a media key (encoded in a Media Key Block) and the Volume ID of the media (e.g., a physical serial number embedded on a pre-recorded disc).

Each device adds its own secret keys together (using unsigned addition modulo 2 56 ) according to a KSV received from another device.
SPDC executes code from encrypted content on a Blu-ray player. When releasing new discs, content providers can update the code, adding protections against previous circumvention methods. DRM systems in which keys for encryption and decryption do not change can be attacked with one compromised key, allowing decoding of all content using that key ...
