Digital Rights Management (DRM) is a type of intellectual property control employed by many industries to protect digital content from illegal use.
This category is for sites on the DVD encryption system, which is called the "Content Scrambling System" (CSS) to prevent the unauthorized duplication of DVD contents.

The release of a simple program called DeCSS allows users to store and view DVDs from a computer hard drive, and has resulted in a storm of legal action and controversy on to what extent consumers should have rights to control media they purchase.

Please do not submit sites that are just trying to sell DVD CSS software.

On October 31 of 2005, users discovered that Sony BMG distributed hazardous software on their copy-protected CDs called a Root Kit.
