Blu-ray Disc with BD+ back-up with Slysoft
BD+ recently became available and Fox was the first to implement it on such films as The Day After Tomorrow and Fantastic Four: Rise of the Silver Surfer. Both HD DVD and Blu-ray Disc (BD) use the same AACS encryption but Blu-ray added another layer called BD+ with dynamic encryption keys supposed to prevent piracy, and is a selling point to the studios from the BDA.
When AACS was cracked, Fox and MGM halted their BD release schedule for six months while preparing BD+. Now that this layer is also allegedly cracked, I hope the studios don’t drop out entirely.
Currently there are numerous legal battles in the courts of North America and Europe over the legality of creating persistent copies of CSS encrypted DVDs. The Digital Millennium Copyrights Act (DMCA) makes it technically illegal to break the encryption. Previously courts have sided with the consumer’s right to back-up their owned content, so the DMCA has been challenged by consumer advocates. Ripping a copy and distributing it for non-personal use has always been considered illegal.
