One user, "honai," explained that the processing keys are in essence owned by the consumer and subject to fair use, while the SlySoft software crosses a line: "Processing keys are inherent properties of the media, whereas the private host certificate is a document issued to Cyberlink by the AACS-LA," honai wrote. "But I agree on the device key, it's also a proprietary entity that belongs to Cyberlink, and you should have a valid, licensed copy of PowerDVD in order to use it.
