Question

How does Patronus work?

Answer

Patronus is a passive anti-rip solution that encapsulates image files on a DVD disc causing access to the content by common ripping programs to be controlled. The original media content is not modified and play-back quality remains unaffected. This is achieved by introducing copy control encapsulation in areas of the disc that are not read by DVD players during playback. Copy controlled discs are designed to provide effective speed bump protection from unauthorised casual copying. Copy controlled discs have full DVD player playability matching that of unprotectedDVDRs. Menus, special features and extras are unaffected and remain as the original.
