from what I remember, an inaudible tone is part of the soundtrack. if the playing device "hears" this tone, playback is not possible, regardless of hdcp.

And if this is true, give it a month if that and some nerdy 15 year old will have cracked it.

Ever.

Atleast they weren't suprised with this leak like they were with the last one.

COUGH AACS COUGH.

that can be beaten just as well - once they find out where those audio tones are, a program can re-encode the audio to remove it.

its not that its uncrackable, its just gunna take some time to do it.

It's called Cinavia. I started a thread about it on PS3 here: Sony Adds Cinavia DRM Protection in as Automatic ...

And thus far, all processes that remove it are destructive to the audio. Can't losslessly rip it.

so far.

i have no doubts that it will either be 'cracked' to allow it being stripped or bypassed entirely, via software on PC or mods on the playback devices.

No, there is nothing to crack. It's not encryption or key based. It's an inaudible to humans audio watermark. Removing a watermark of any kind is destructive, period.

The only way to bypass it, is to use a player that doesn't support it. It's not a big deal yet, as only the PS3, and one or two other players actually support it. And only one BD has it so far. It's being used mostly in cinemas to stop CAMs, but it could become a large issue if it takes hold in the BD market.

I'm kinda confused by this key leak and the reaction it's getting.

From what I know (or rather what I think I know) the biggest practical use of this key is just making third-party (unlicensed) HDCP-compliant devices.

It doesn't make sense to capture a blu-ray stream for the purpose of direct copying because the bandwidth is too great.

It's already plenty easy to rip a blu-ray using software like AnyDVD and encode it using something like Ripbot264.

Yeah, that's what point I was trying to make with my earlier comments. It only effects displaying the content on a screen, not ripping it.
