Is Bystander = Muslix64.

Just joined and pretty much tells how to get the
keys but without telling all of it.
Sounds like Muslix, and using a second screen name will
lessen the chance of getting traced and sued.

I think Muslix is from Germany, where the cereal is from and a land where Commodore 64 was a hackers first toy.

This is just speculations, and Mods can delete this post if it's
out of bound/irrelevant.

Good morning all! I see there's been much activity since yesterday...

There is no need to bring the keyed but unencrypted files to a licensed HD-DVD replicator to get them encrypted... here is one example of software on the market :

Eclipse Data Releases High-Speed Blu-ray AACS Encryption Software
"We knew that we needed to minimize the impact of moving encryption into the premastering process"
Premastering is what you do with the Sonic package. This means you can get secondary software which will take the fileset made by Sonic and convert it to a fully AACS-encrypted fileset or ISO image.

Sonic only adds AACS information to DDP images, also known as PlantDirect:
"A powerful add-on option for Scenarist Studio (SEN-3101), PlantDirect Tapeless Premastering allows DDP file sets to be written to hard disk, rather than to DLT, enabling delivery of DVD masters for replication via the Internet saving time and money on physical shipments."
DDP is the industry standard for disc imaging, and was established by a company known as DCA Inc. They established the standard, so it should surprise nobody that they also make a product called Blazer:
Blazer is an application designed to encrypt a DDP V3.0 HD ROM image with the Advanced Access Content System (AACS) encryption. Blazer automatically recalculates the HCRC in the AACS encrypted image.
I contacted the company by phone this morning, and found out that the software, while it runs on XP (screenshot), only comes bundled with a workstation machine with RAID, etc. The cost is probably high, I didn't ask, but will do so later today and report my findings.

Other than this it seems the Sonic product "DVDit Pro HD" can author AACS protected Blu-Ray DDP filesets, but it doesn't have HD-DVD functionality.

Finally, an email was sent to Eclipse requesting a price quote for their EclipseSuite + AACS addon software. It runs on any hardware (ie. software-only); the specifications page states that it will run on Windows NT 4.0, 2000 and XP. It also seems to need an Adaptec SCSI controller, but those are cheap.

I don't think it matters who Bystander is. He seems like a knowledgable person and it looks as if he would be an asset to this community. You shouldn't question the identities of people. If they want you to know who they are then they would tell you.

Yes it is speculation and you should use your own judgement and delete it yourself if you think it is out of line.

Please, it shouldn't matter who one or the other is. What they post is important.

There were actually other files with the PlantDirect image, they might be important if anyone manages to get hold of Blazer or an equivalent. Note how small it all is when RARed, I suppose it's the blank revocation files.

http://www.filehost.gr/883400

The IMAGE.DAT is the same as before.

I was going to make a short video with more than just a blank screen and maybe audio too, but, this sounds really stupid, I couldn't think of a way to encode just a few seconds of video with MainConcept... Any idea how to make a short animated clip with AVISynth?

Simple solution: use Colorbars(width,height) and ShowFrameNumber().

Some observations for those with HDDVD drive and know, what OllyDbg is.
Seems, HDDVDAdvNav.dll is a module where stuff is located.
Here are all AES function calls:
Code:
;-----------------------------------------------------------

Colorbars() makes 1hr of video by default. How can I change that to something shorter?

Sounds like Muslix, and using a second screen name will
lessen the chance of getting traced and sued.

I think Muslix is from Germany, where the cereal is from and a land where Commodore 64 was a hackers first toy.

This is just speculations, and Mods can delete this post if it's

Sigh.... Why won't some posters read what we type and read the rules? Strikes issued.

Ok, here's another image with Colorbars and a Framecount instead of nothing. Analogue output is now allowed instead of constrained.

http://www.filehost.gr/73129

The volume and title keys are in the discinfo.dat file (volume key first, then title key).

Now there's probably not much else to play around with until someone can get hold of Blazer of figure out how to encrypt the video.

I'm designing a GUI for the HDDVD backup and attempting to make an easy way to enter the keys in as you get them.

Since I don't have an HDDVD player it makes it impossible for me to change any of the source that muslix provides and guarantee it works, and as such I will simply make a wrapping gui for the backup classes. If he continues to put up future releases it should be easy to plug in the new version into the gui.



This is a 30 second design in java, but it makes it easier to use. I'll be posting it soon for those who want an interface rather than command line.

@Borbus: Thank you!

I haven't yet receive a reply from Eclipse. It seems that for now, the best way to verify BackupHDDVD's functionality is to obtain an HD-DVD drive, AACS-protected HD-DVD disc, and player software.

The Title Key must be available in the clear during the entire playback process, as it is needed to decrypt each chunk of data as it is read.

Keeping the Title Key scrambled using the player software's algorithm or encrypted from disc would place a heavy burden on the CPU during playback, as it would have to be repeatedly decrypted to be used for chunk decryption, throughout playback.

Considering that most machines are only just able to decode 1080p content alone, it seems unlikely that software authors would cripple their product's performance using such a method.

if you guys want some hd-dvd's to test you can get 2 for 2.86 delivered from a mis-price on play-asia: http://www.hotukdeals.com/forums/showthread.php?t=42021

@ polly - great work, release the sourcecode when your done. also change the image of the dvd to this:

I believe they have, in fact, done so and the title keys may not remain in the clear for long. The player behavior I've seen is consistent with the code snippets Bystander posted. The player accesses the encrypted title keys in memory every few hundred milliseconds or so. I've also seen it clear heap memory.

The CPU load is enormous and regenerating keys whenever necessary, on the fly, could easily be accomplished, within the high load. Besides, compared to decrypting the content, decrypting the keys should not result in much additional load. I have a computer that plays high profile AVC HD with CoreAVC nicely. The computer can't even come close to decoding a VC-1 HD-DVD without dropping frames all over the place. The developers were probably more concerned with implementing DRM than realizing performance.

Bystander's suggestions are useful, based on the behavior I've captured.

So basically we can either add the steps in that were suggested or create a breakpoint JUST before the heap clears and instead dump the memory. What are you all using to play this.. My version of WinDVD HD crashes when I load the file..

I just received an email reply from the folks at Eclipse, regarding the costs for an AACS license (required before Eclipse will sell you their product):

"It's pretty expense. You can find more information at: http://www.aacsla.com/home

I think the adopter agreement costs about $20,000 per year, and then AACS collects about $2,000 per title, and $0.04 per disc.
"

Sounds like a reasonable approach to try. I suspect that most people are following Muslix64's suggestion to use PowerDVD 6.5 but he said other players may yield keys too. Try launching or enabling your debugger after a title is playing and remember that the AACS spec says stuff must be cleared when the player is stopped. I don't know about pausing play.

It seems amazing, on how one posting has created a lot of conversation on the subject in question burning a HD-DVD and yet no one is able to burn one. Will sit in the background and see what this thread leads to.
