New DVD copy protection on DVD's introduced by Sony

[BJ_M]

Sony has a new copy protection called dynamic encryption ... as soon as it was released (currently it appears, only in Germany at the moment), the new system was defeated ...

There are accually two systems (one not by sony) , the second system has to do with "ring protection" and the Sonysstem is called ArcCOS ..

you can read about the Sony system here (only on dvd5) http://www.sonydadc.com/file/ARccOS_Flyer.pdf (not very much to read)

as for defeating this system and the ring system ..


BlindWrite with Ring-Profile (for ring system protection)
and DVD-Decrypter for the Sony system:

If you use DVD-Decrypter you have to rip without the first 3 cells of the movie, then use ifoedit or dvdlab and rebuild the dvd ..

We have to go back to the hard to to back up DVD's until the next release of DVDshrink come's out LOL.

rule #1

If it can be played, it can be copied.

Rule #2

See rule #1

When will they ever learn? :P

[gitreel]

If they want it to be uncopyable, they will not release a movie at all. It is kind of hard to copy something that was never released.

[vioxx]

Yes! CAN play then CAN copy!!

Where is DVD Shrink v3.2?

[r0bas]

Where can I find the Ring-Profile for Blind Write?

I want to copy a DVD with this lock (Wrestlemania 3) and I can't find the proifile anywhere!

Thanx

PDF says the DVDs are 'copy-proof.' Some things I've just learned not to say...like

'NOBODY can do that.'

'She'll NEVER find out.'

'It's COPY-PROOF.'

Thus endeth the lesson.

How much do you think they paid for that system?

[GKar]

All these guys do is provide entertainment and challenge to DVDDecrypter, DVDShrink et al.. and temporarily irritate the rest of us.

PS: I hope they paid out the ass for this crap. :P

They claimed that CSS would be uncrackable, too. Then someone over in Norway discovered that it was only a 30-bit key that they allocated to makers of players and discs alike. Given that secure Internet connections use something in the order of 128-bit keys, I'm still surprised that CSS are surprised they got broken.

It's as if the people making these encryption systems are daring hackers to break them down. Is it so they can bilk the studios for more later?

[ViRaL1]

I wonder if they'd do better distributing movies on low-quality media.

Nah, someone on the inside will set it free, like all of those pre-release movies that the MPAA used as an excuse to crack down on dvd copying (they apparently missed the time moving forward part of the concept of causality).

wasn't it something like a company forgot to secure the encryption on a software player and someone cracked it really easily and worked out the rest with no effort or somthing?

Nothing so romantic, really. XingDVD's encryption key was broken by a programmer who had the patience to sift through all the lines of code, and then numerous others were derived simply by guesswork. The DVD Consortium could have chosen to implement a new encryption system, or realised that they can no longer constantly deny enthusiasts of what they want. Instead, they chose to make an example of Xing and wrote them out of the DVD specification. All those Xing owners were terribly incensed until they got a hold of DeCSS and could watch their DVDs using Xing anyway.

As my once editor put it, CSS was far too tempting a target for hackers to just let it go. That it had such a short bit-length all but ensured that it would be broken sooner rather than later.
