Myce user Macrovision3500 reports on our forum that the Cinavia copy protection is broken by using freely available and opensource software. Unfortunately the method has a drawback, it degrades the audio quality of the movie. By using the opensource audio editor Audacity with settings as stated here you can create an audio track from which the Cinavia protection is removed.
Macrovision3500 has tested the solution with his Playstation 3 with the latest firmware and confirms it works. While the audio quality might not be acceptable for many users, this is a great proof of concept. The Cinavia protection works by adding a watermark to the audio track of movie. Therefor many belief it should be possible to remove the protection by making changes to the audio track.
It seems that this technique indeed breaks the Cinavia protection. The method can probably be fine-tuned and might become an excellent method to enable users to make backups of Cinavia protected discs.
There are other ways of backing up discs that are protected by Cinavia. With the paid applications AnyDVD and DVDFab it’s possible but they require frequent updates. Also the developers of DVDRanger claim to have a working solution, unfortunately it has not been released yet.
