Are Blu-Ray copies vulnerable to retroactive lockout?

[rolypolyman]

I've started backing up Blu-Ray discs with a decrypter and BD Rebuilder, but I am wondering whether there is any danger of retroactively losing all my backups at some future date. The scenario I'm thinking of is say in 2011 my PS3 gets a system update, which has a payload containing some sort of new Blu-Ray firmware that specifically looks for questionable discs, based on signatures left by DVDFabHD or whatever. I understand they don't want to shut out original factory discs, but might copies be vulnerable?

I also read in the Wikipedia articles that Blu-Ray has a provision for some sort of lockout based on watermarks, but I'm not sure what that entails. Would a digital watermark be lost in BD50->BD25 recompression?

Hi!

Regarding your question about watermarks, a trial balloon has already been floated.

Sure; easier yet, the PS3 only needs to be told "don't play any BD-Rs or DVD-5s or -9s" (indeed didn't Sony already "update" the PS3 to not play any AVCHD discs?). I think LG did this with their BH200 for example. Nothing to stop the mfr from doing this except for the firestorm it might create with their customers.

Rule-to-live-by: whether for the PS3 or any other settop player, don't do a firmware update unless you know what you're getting-into and are certain you need it, or know you can fall-back to an earlier release.
