Congrats! NO DRM! Lets hopefully get this stuff somehow easily bypassed in hardware!

I'm not for piracy at all - unless you want to count allofmp3 ;) But that is its own thread...

They should just give movies away and put a bunch of product placements in the movies to rake in advertising $$$'s.

Maybe even throw in a commercial into the story line!

Superman: And now, Lex Luthor, I will finish you off ::eyes glow red::....but before I use my heat vision to fry you, I'll need to apply some Visine. Using heat vision can really make your eyes dry, and nothing takes the red out like Visine.

Lex: Where can I get Visine?

Superman: It's available at Walmart, Walgreens, and most major chains. Now...back to business!

hehe, too true. So much time and money gets wasted making "secure" software/hardware, but the amount of time needed to Crack it remains the same.

I'm sure the people making it know it is going to be cracked. I wouldn't be surpised if some of them helped in the cracking

Now the same thing has been done to Blu-ray:

Looks like neither format is going to win the DRM war.

Did you happen to read the HD-DVD link?

The encryption for HD-DVD wasn't cracked. It was a flaw in PowerDVD that allowed a user to grab the key from memory when PowerDVD played a movie.

That's not cracking the encryption, thats just a hole in a piece of software.

If it's on the PC, it'll be cracked at an amazing speed. Is there any software that hasn't been cracked? Whoever designed the Xbox 360 was smart. It's a closed interface with constant CRC checks making it extremely difficult to crack. But once something's on the PC, they can say goodbye to any security measures.

Virtual machines, debuggers, memory watchers will never be stopped.

A hole that has so far yielded 72 casualties (i.e. decrypted HD-DVD discs). I don't know whether or not they'll be able to do anything about it now. They certainly can't if the people have already ripped it using those keys. The customers get screwed once again, I for one am glad I haven't bought an HD-DVD or Blu-Ray drive as its key probably would have to be revoked. I don't know what they're going to do with all the Xbox HD-DVD drives. Or maybe it's the software (PowerDVD) they'll have to do something about.

PowerDVD is going to release an update most likely.

They'll have to get that patched up quickly and just chalk up the 70+ disc as casulties.

Is there something with the disc encryption that they can change (hash?) that will generate a different key for future printed batches of the movie? Or is it all simply tied to the unit itself?

As far as I know each HD-DVD title has a Volume Key and that is what is placed in memory or registers during the disc playing process (it is swapped in and out quickly however). There is still no automated way to get this but it's hardly a problem as the titles are being decrypted like hotcakes already. I believe the Title Key (the key that exists for each chapter on the volume) cracking is automated.

You do raise a good point. They could just change the Volume Key in future pressed versions of the disc, however they would also have to add PowerDVD to the revocation list. But that'll probably be cracked too anyway. I'm not even sure if they can add certain software to a list or not, but it certainly seems as though it'd be just as easy to crack.

Maybe the check is not executed on the host computer but is instead run on some internal chip. For example, the software sends a hash and the drive receives it, verifying that the hash is not on its denied access list. But all you'd have to do to get around that is send a valid hash from an insecure program. Changing the hash sent from the program couldn't possibly be rocket science. It, like everything else, is in full human readable form somewhere in the sequence of all the register accesses.
