![]() ![]() ![]() It is a form of copy protection that uses 40-bit encryption. Copies will not be playable without a key which is not writable on DVD-R or DVD-RW discs. With this technique, the work is encrypted using a key only included in the firmware of "authorized" players, which allows only "legitimate" uses of the work. Later, more DVDs attempted to augment CSS with additional protection schemes like ARccOS Protection, which was made by Sony and deliberately creates corrupted sectors on the DVD so as to cause copying software to produce errors. There are lots of other copy protections for DVDs. Of course, many protections are also used on Blu-ray, and we won't talk about them one by one. ![]() What if one wants to copy protected DVD/BD content to hard drive for backup or later editing? Is there any powerful tool designed for this purpose and costs not even a penny? Then DVDFab HD Decrypter is here. ![]()
