and about the "protect your id thing" why should he, he did nothing wrong and nothing the industry didn't except to happen.
And everyone involved in AACS knew this would happen, their is no way to protect against such stuff on the PC Platform as we have it today, see all the HD-DVD/Blue-Ray Player and PS3/XboX 360 those are Platforms that can be called Secure but the PC isn't yet but industry is working on it to make it more Secure the first steps are made TPM 1.2 and Vista more will follow in the Future.

i think their lawyers would disagree!!! the industry has accepted it will be cracked, however its still illegal and they will indeed hunt him down.

i dont want this guy to end up in jail for 5yrs, he's done a great job

I love it. It IS 100% LEGAL (Read you lawbooks on this!!!) to make a COPY of media you OWN (Reason why he did this, as he said, the media is VERY touchy to scratches.) "An individual is allowed to make 1 copy, per for archive purposes, of the media he owns. You, however, are not allowed to sell the copy, per said, for profit. "

It is the same reason ALL the dvd copy (ALL LEGAL) software, as well as all CD backup software/Music CD backups, Audio rippers to devices ('Because you own the original' in there eye's).

It's irritating to still watch people "Eh-eh-it's against the law!!" when they clearly don't understand the law one bit and THINK by assuming what they hear or there own believe's. I've actually asked the written law with my lawyer and how it's translated by definition in the courts systems. And more or less said the same thing i researched on the internet myself. I would agree to not post the source, so they don't learn so quick their mistake's however, and keep it the execution file/docs only.

Moves to rein in the DMCA have been initiated in the U.S. Congress, where at least two bills have been introduced that grant exemptions for consumers who crack encryption for certain legitimate purposes--for example, to make a backup copy of a legally purchased DVD.

Yeah, because it turned out so good for Lightning UK when he didn't release the source code and they came after him for DVD Decrypter...

I would take the advice to play it safe and do what you can to protect yourself, and get that source code spread across the net as far as it will go...

Sure, whatever, that's nice. But until those bills are passed though, breaking a copy protection measure--even for the purpose of asserting a perfectly legal right--is illegal and punishable by prosecution. Thus, heroes the likes of DVDJon and now muslix64 need to make sure their identities are protected. The two **AAs have been churning out lawsuits against good people for a couple years now. It's easy for them to get YouTube or some other site to cough up an IP addy on this guy.

I'm also doubtful those bills you speak of (assuming they are reintroduced when the new congress convenes) will be passed anytime soon. Past history has shown congress to be very friendly to the media industries. For example, it's the US that is holding back Russia's entry into the WTO, and AllOfMP3.com's existence is cited as a primary reason.

If I understood correctly, the Title Keys were yanked from active memory, which would render revocation of PowerDVD's key moot. The player's key decrypts the encrypted title key which is the key needed to decrypt the video (somebody correct me if I'm wrong here).

Hence, if all you need is a way to yank the Title Keys, What's to prevent the next version of PowerDVD (or any software player, for that matter) from falling to this same tactic? They could also try to deauthorize the old software players and find some way to scramble the title keys in memory on the next versions, but reverse engineering the software itself to find the scrambling method will reveal those keys once again.

However, even if they do decide to go to an extreme and yank software players off the market (at least, for any OS other than the ass-puckered WinVista64), I could easily see someone cracking open a perfectly good HD-DVD player, probing the memory, and just create a list of HD-DVD keys that gets posted to some online website. The only trick is that you'd need to keep REAL QUIET on what players you're modified to pull title keys from.

That obviously would make it difficult for just anybody to make their own keys, so I foresee key distribution as the next big craze. This would relegate disc backups to an as needed sort of thing. You can back up a disc you bought if you really want (if, for example, you want to watch a movie on your laptop but prefer to leave the disc at home), but you'll need to go online and hunt down a key first.

Actually in large parts of Europe it's not illegal to make a copy for home use, but it IS illegal to break copy protections, even on your own bought movies, therefore usage of this tool is illegal imho

EXACTLY. in the u.k the DMCA (digital millenium copyrights act) forbids circumventing copy protections. im pretty sure there is a law for the u.s too. if it dosent have a copy protection on a disc then you can indeed make 1 copy (aslong as you keep both of them and not transfer to a 3rd party).

cant remember what the U.S law is for this as im from the u.k.

i really hope a GUI of the 2nd jan of this tool is made, GUI's for the win!

Let's please focus on the technical and practical aspects of this exciting new program rather than debate legal issues in different jurisdictions.

Thanks folks and thanks to muslix64

The US Law is the DCMA. Are we not governed by the Copyright, Designs and Patents Act 1988 in the UK? Is there a newer one that gives DCMA like restrictions. If so what is it?

Just found this looks like you may be wrong in name, right in principle: http://www.out-law.com/page-4168

should have posted the source from a internet cafe or library or something. Then don't have to worry about getting caught by IP/ISP But legal or not it doesn't make much difference because people will do it regardless.

For those who may get this error:
Error: no `server' JVM at `C:\Program Files\Java\jre1.5.0_10\bin\server\jvm.dll'.

do this:
copy
C:\Program Files\Java\jdk1.5.0_10\jre\bin\server
to
C:\Program Files\Java\jre1.5.0_10\bin\

Backup HD-DVD V0.999 Starting
Usage: BackupHDDVD SourceDrive Destination_directory
Example: BackupHDDVD f: e:\movie\somemovie

Download JDK from:
http://java.sun.com/javase/downloads/index_jdk5.jsp
JDK 5.0 Update 10 is what i used (full offline version)

bob0r,

Am I correct to take your posting as confirmation that you've used this tool and that it works?

Can anyone else confirm that they've successfully saved an AACA-protected movie to hard disk and then been able to play it from there?

The Java source code is only an implementation of the AACS decoder which in itself is only a wrapper around AES. It looks like the OP found a way to take the title key through out of a HD-DVD player through reverse engineering, but he can't tell us because if the movie studios know which player has a weakness they'll revoke its player key.

It's much better to wait with that until after there's more HDDVD/Bluray releases because then doing a key revocation would
a) Be much less useful because there's already more movies out
b) Create more resentment towards movie studios among the consumers if they can't play a newly bought movie because their player was cracked

Are the title keys shown in the YouTube video real?

hmm, but if that player is a software player like PowerDVD, (like version 6.5 which is shown in the YouTube video)- then aren't studios are out of luck as people will always be able to install that exact same 'old' version of the software player on their own computer that is not connected to the internet (and can thus not get revoke updates) and thus use that to grab the keys from the RAM memory when it is playing/decoding the movie?

By the way, did any notice that YouTube video shows the title keys of some movies when he films the contence of his TKDB.cfg file? if those are the real keys, then people with the knowledge and software to scan/dump the active RAM memory should be able to search find one of those specific keys if he/she have one of those exact same movies, and then he/she can use that as a map to find the location where keys of others movies are 'stored' in the memory while the movie is being played/decoded by PowerDVD. As I assume PowerDVD always stores that key in memory the same way in the same version of the software?

For example, it's the US that is holding back Russia's entry into the WTO, and AllOfMP3.com's existence is cited as a primary reason.
It could happen. Over the years there have been more and more exceptions being added to the DMCA.

FWIW the DMCA is not something that the US congress wanted per se, at least not in the lobbying sense. The reason we have the DMCA is to be in accordance with the WTO and WIPO treaties. In fact when that and the CTEA were challenged by Lessig and his crew, the supreme court cited these treaties as the reason for justifying these laws as being constitutional, because the constitution says that treaties are the law of the land.

The US happened to be the first country to adopt the policies of these treaties in the form of the DMCA and the CTEA. Because of this many people on the internet go around blaming the US for being the reason that their country adopted similar, often more restricting copyright laws (I know many aussies that do this especially.) This isn't the case actually. These countries are enacting these laws as part of these treaties as well. In fact if you look at the tenets of these treaties, they call for far more restrictive policies than what the DMCA calls for.

Whenever you see some trolling site like slashdot or something mention that some country is enacting a new "Super DMCA" it is actually that country falling more in-line with the treaty than the US is.

If you ask me, eventually the DMCA will eventually boil down to this: don't decrypt or talk about decrypting any content unless there is significant fair use for doing so. E.g. backing up a DVD would be allowed, but stealing cable by decrypting the signal without authorization wouldn't be. Which I think would be very fair.

But anyway, what's done is done, and I hope this fix stands the test of time. If so, I know what format I'm buying.

Time to tinker with Blu-Ray anyway though, just to make sure the studios don't have anywhere to run. I'd buy you a Blu-Ray drive for the effort if I had the money.
IIRC doesn't blu-ray also use AACS?

In either case I don't imagine it mattering much. No form of video media will ever have a renewable security system, period. With that said, once it has been decrypted, its all over. Whether it happens now or later, it makes no difference in the end. Maybe a little more effort on the part of the crackers and content providers, if that. The AACS standard is for the most part set in stone already, and as we sit, it's mostly broken.

Mostly as in, we still need to obtain some decrypt keys before we can fully decrypt the video.
