DVD Decrypter is a software application for Microsoft Windows (including Windows 7 support) that can create backup disk images of the DVD-Video structure of DVDs. It can be used to image any DVD, but controversially it is especially useful for decrypting copy protected movies. The program can also record images to disc.
Content Scrambling System (CSS) decrypting software (such as DVD Decrypter and AnyDVD) allows a region-specific DVD to be copied as an all-region DVD. It also removes Macrovision content protection, CSS, region codes, and user operation prohibition.
