The copy protection originally designed to protect content on DVDs has been overcome some years ago. What other methods can you find today that movie studios are using to protect their content on DVDs or other optical media?
RipGuard was introduced in 2005 to prevent and/or reduce digital DVD copying by altering the format of the DVD to disrupt the ripping software. Macrovision, who created RipGuard, claims that majority of the population lacks the determination/knowledge to copy a DVD protected with RipGuard.
ARccOS (Advanced Regional Copy Control Operating Solution)is made by Sony & used to protect some DVDs. This protection sets up corrupted sectors on the DVD which cause copying software to produce errors.
Protect Software was altered in 2004 from it's 1996 introduction to focus on copy protection. ProtectDISC Video protects mass replicated DVDs. The software prevents analyzation of the DVD structure, which then prevents copying. It is used by Universal Studios & Sony Pictures Entertainment.
ProtectBURN Video protects DVD copying by stopping ripping software from analyzing the structure of the DVD, also. This process can be performed by the publisher & is used by movie studios to prevent copying.
