It'll be interesting if they haven't.

I'm off to test about half a dozen 2+ year old CAM recordings on my PS3. I'm curious if they started adding Cinavia way back then, when they were planning on adding that protection to HD-DVD.

CAM recordings, yikes, this is going to be...unpleasant, one way or another....

is it properly also the film "Shutter Island" the new protection has?
if he this protection has then, however, this has no effects on playing with the WDTV

Pirates won't be affected if there's any audio track out there without this watermark embedded. They'll simply mux in the un-watermarked audio track and they're done. Most pirated releases aren't doing HD audio anyway, so, a small AC3 track suits them just fine.

I have zero sympathy for anyone trying to watch CAM releases. None whatsoever. The CAM releases are the reason this watermark crap is being used in the first place. Then they got the brilliant idea of applying it to retail BD's. Awesome. Thanks, pirate scene. You successfully screwed those of us trying to backup our legit retail BD's.

No, Shutter Island does not contain this. The Losers is the first retail BD that has it. Anything released previously does not. That's been said a few times now.

I agree, the ONLY reason I downloaded those 4 or 5 old CAM's was to test this. I still haven't gotten my fat ass off my computer chair, but I will let you know if I find anything interesting, apart from shoddy images and crappy camera work .)

Dunno, they used it on DVD-A. Never underestimate the greed of media executives.

The Cinavia that is built into the audio from the source Blu-ray disk, can the same audio with Cinavia be put in the back-up disk after the AnyDVD HD rip?

Since the Cinavia player is looking for the Cinavia it will have it, and the back-up copy should play.

In others words can AnyDVD HD rip the disk and keep Cinavia in the audio after the rip?

Currently we're debating on how to get the cinavia watermark OFF the disc.
As soon as we have accomplished it, any suggestions on how to get it back ON are welcome, but not before then

My question is if it's on the backup just like the original, what is missing from the backup that is activating Cinavia? The BD protection? Couldn't you just make a protected backup, an exact copy of the original, therefore tricking Cinavia into thinking its working as expected?

I suppose there is that. All I wish to do is put my legally purchased BD's on my HTPC so I can serve them across my network to any machine in the house. I've found MKV to be the most efficient container to do that. As long as I can continue to do that, great. But it's going to require non-commercial software to pull that off. So be it I guess.

So, let me get this straight. You're proposing we copy a copy protected disc without removing the copy protection in order to trick a watermark embedded in the audio signal into not telling the player to disable the audio? Fascinating. You do realize copy protection exists to prevent you from copying an original, right? If we were able to copy it without removing the protection, there wouldn't be much need for AnyDVD nor would it be a very good copy protection in the first place.

No. Only pressed BD's can contain AACS. IIRC a BD player is supposed to refuse playback of a AACS protected disc if it's a BD-R(E).

So yes, the missing part is the AACS encryption.

It's more than just that. There's a disc ID that can't be copied onto a backup that is used as part of the AACS decryption process. The only reason "protected backups" work is because AnyDVD has the title key for that particular disc. The disc *ALWAYS* gets decrypted and if applicable BD+ protection removed before the player gets it when dealing with backups. I think people get confused with the idea of a "protected backup" somehow magically working with all the protection in place. It simply means that AnyDVD is working its magic on the image in realtime instead of when you ripped it. To the player, a protected image is no different than a ripped, unprotected image.
