"BD+ is a ground-breaking security technology which is designed to enable HD optical formats to recover from major piracy attacks without revoking players or affecting legitimate users. It is a safe-guard that is only available for studios releasing titles in the Blu-ray disc format. BD+ does not exist for the HD DVD format, and was not compromised in the Muslix64 hack." the email reads.
"A report released by Independent Security Evaluators affirmed that CRI's Self-Protecting Digital Content, the principal architecture behind BD+, significantly enhances the anti-piracy measures in AACS by providing critical format security needs not addressed by AACS alone." it continues.
BackupHDDVD recently got an upgrade to v1.00, adding support for Volume keys to be used.
