コピーコントロールCD
In August 2009, the DVD Copy Control Association won a lawsuit against RealNetworks for violating copyright law in selling its RealDVD software, allowing users to copy DVDs and store them on a harddrive. The DVD Copy Control Association claimed that Real violated the DMCA by circumventing anti-piracy measures ARccOS Protection and RipGuard, as well as breaking Real's licensing agreement with the Content Scrambling System.
