How effective is Patronus?
Very effective, but it won't prevent ripping in 100% of cases. The goal of Patronus is to make DVD video copying very difficult for the average person, thereby protecting the rights and profits of copyright holders. It is intended as a robust yet transparent anti-rip solution that can significantly help to prevent unauthorized copying of discs. Further, it is an upgradable software solution. New and innovative development continues to ensure that it provides the most reliable, efficient and easy to use anti-rip copy protection solution available.
