Ripping DVD is a good way to keep a backup and stream video over Internet, or transfer video to portable devices. However, most commercial DVDs are always protected by CSS (content scrambling system), a defense against movie piracy. CSS encrypts data with a special key. The key is not a secret to DVD playing software developers who need it to read the information.
If you want to decrypt and backup DVD, technically, you need seek help from some DVD decrypting software available that can help to decrypt a protected DVD. There are several programs that can successfully decode the CSS encryption. One is CloneDVD that not only removes the protection, but also gives the user the luxury of ripping specific portions off the movie. Plus, it can copy them to a recordable DVD. And next we will show you how to decrypt a DVD and backup it.
