I'm not sure how much more the Blu-ray player is to make over the HD-DVD player since they are both using blue laser's.
I thought this was in interesting bit of info: (Wikipedia)
Muslix64's exploit
On December 26, 2006 a person using the alias "muslix64" posted a utility named BackupHDDVD and its source code for a working AACS decryptor on the doom9.org forums. The program is not an exploit or hack per se. Rather it is a tool that can be used to decrypt AACS protected content once one knows the encryption key. As such, it is no surprise or indication of vulnerability that such a program is possible and it can be seen as merely an implementation of the publicly available standard AACS Guide. However, Muslix64 claims to have found title keys in main memory while playing HD-DVD disks using a software player, and that finding them is not difficult.[13] Details of how to do this have not been revealed.
On January 2, 2007 "muslix64" published a new version of his/her program, with volume key support.[1]
Cyberlink, developers of PowerDVD maintain that their software was not used as part of the exploit.[2]
The claimed attack (extraction of the encryption keys from a software player) highlights the inherent weakness of software movie players for the PC platform. The use of encryption doesn't offer any true protection in this scenario since the software player must have the encryption key available somewhere in memory and there's no way to protect against a determined hacker extracting the encryption key (if everything else fails the user could run the program in a virtual machine making it possible to freeze the program and inspect all memory addresses without the program knowing). Avoiding such attacks would require changes to the PC platform (see Trusted Computing) or that the content distributors do not permit their content to be played on PCs at all (by not providing the companies making software players with the needed encryption keys). Alternatively, they could use the AACS system's revocation mechanism to revoke a specific software player after it is known to have been compromised. In that case, the compromised players could still be used to break old titles but not newer releases as they would be released without encryption keys for the compromised software players requiring hackers to break other players. The latter alternative is not a desirable option, because it would result in legitimate users of compromised players being forced to upgrade or replace their player software in order to view new titles.
On January 13, 2007 "LordSloth" on Doom9 discovered how to grab the volume license keys from WinDVD's memory. With that discovery, it became possible to take backup of HD-DVDs. Later that day, the first pirated HD-DVD, Serenity, was uploaded on a private torrent tracker. (end quote)
Haven't seen anything on pirated blu-ray yet.
