There is still a long list of modifications that need to be made to the BackupHDDVD before multi-core support is anywhere near a top priority.

Proper handling of PCKs and ability to deal with IME are the major ones.

Example
javaw -jar BackupHDDVD-GUI.jar
I just double-clicked on BackupHDDVD-GUI.jar and it opened like it was an .exe file. Doesn't this method work just as well as opening it from a command promt?

Great logo, but a couple of things:

1) Trying to keep things legal, I don't think basing off the existing HD DVD logo is in fact legal. I do beileve there is some copyright on that since it is not parody etc.

2) It looks great, what font did you use to match the DVD font? I looked at one point for a font but could not find one.

Not trying to be a buzzkill, just thought I would mention that!

Bye.

I adapted BackupHDDVD-GUI to check the correctness of the Volume Unique Key using CMAC algorithm, but since I don't have a title key file myself, I'd also like to receive some sort of valid title key file to test the changes against.

I set up a project at Sourceforge for BackupHDDVD. I should know if it's approved by Friday.

Multi-threading this app wouldn't do a whole lot to help. What's slowing it down is 1: the maximum bitrate of the USB connection / drive read speed, and 2: The fact that this is a Java program using its crappy crypto functions.

You should decrypt the movie directly from the HDD, my quality of the movie is better now and it's faster!

I seem to have no trouble with speed. Mine takes ~1hr with a P4 3.4 2GB of RAM. I dont think thats too bad for 20+ GB

Just to let you people know, i've started working on Blueray keys and have created a new thread for those interested.
Yep, i bought a 800$ Blueray burner for the sake of the community

bloody hell Janvitos!!!

$800 is a hell of alot of money, which burner did you buy? you should have waited for the new combo writer from lg, it reads hd-dvd's and burns/reads blue-ray @ 4x i think.

let us know the progress with decrypting blu-ray.

that makes no sense what so ever.. how can the image be worse just because the ripping to HD from the disc is slower??? its data it doesnt change unless its told to like in transcoding eg: dvdshrink where it re-adjusts bitrate.

so your saying its quicker to copy the encrpyted files to the HDD which will take a while anyways for 18-20gig and then run it again from there to another HDD through backuphddvd and this will be quicker and give you better Q??

Be careful please about sharing EVO files (or other copyrighted video files) or mentioning the sharing of them here.

We allowed publication of title keys on the basis that the people who could use them actually had the disks anyway. We do not make a presumption that someone has rented a disk and is using a published key.

Asking for the video content itself (or a part thereof) is entirely another matter - it needs little thought to figure out you don't have the DVD.

Sharing files are best done via PM and certainly not in open forum and we at Doom9 do not condone the sharing of files. Please refer to rule 6.

Regards

I don't have a HDCP compatible graphics card, so I'm thinking about using BackupHDDVD to be able to play my HD DVD discs. Now my question is:

Can I find out the keys of my own HD DVD discs by checking WinDVD memory without having a HDCP compatible graphics card? Or won't WinDVD have the keys in memory if I don't have a HDCP compatible graphics card?

Thanks!

Hi everybody,

The following is based on what I read in the docs founds at : http://www.aacsla.com/specifications/

And specially this one :
http://www.aacsla.com/specifications...orded_0.91.pdf

I have a few questions about Sequences Keys, or Volume Unique Keys Variants (chapter 4). Well, first my english is not good enough for me to understand what exactly they are used for and how they work (first question) although I undestand that it's a revocation-scheme protection mecanism similar to the MKB.

Second question, BackupHDDVD seems to work with Volume Unique Keys only, so what are the Variants used for ? Section 3.5 states that Title Key is computed with this formula : Kt = AES-128D(Ku, Kte). Kte being the encrypted Title Key and Ku "one of the volume unique keys defined in Section 3.3". Section 3.3 explains how to compute Volume Unique Keys (Kvu) and Volume Unique Keys Variants (Kvvu). So that would mean that we can feed BackupHDDVD either with a Kvu or au Kvvu and that you only need one of them to decrypt Title Keys ?

Well, I'm confused
