CopyBlock contains the same Macrovision anti-copy (ACP) and anti-rip (based on RipGuard rip-deterrence) technologies used on billions of DVDs worldwide.
The comapany admits that piracy cannot be easily stopped. However, the technology provides a higher level of protection than CSS, which is compromised by free ripper programs. According to the company, casual DVD pirates won't spend more than 30 minutes trying to copy. When frustrated from copying or ripping a DVD, more than two-thirds say that they'll usually buy the DVD instead.
