Can the in memory key searching trick for AACS cracking be used on CPRM cracking?

Detecting the watermark is one side of the story. Removal of the complex echo very hard to achieve.

Verance told us about existence of detector/remarker products (see http://www.verance.com/vcms/products_consprod.html). This way echo doesn't have to be removed, only CCI bits should be set in "copying freely" position.

command example:
dvdcpxm.exe D:\AUDIO_TS\ATS_01_1.AOB C:\dvda_rip

the new tool can decrypt CPRM/CPPM protected video and audio, i.e. both CPRM/CPPM protected AOBs and VOBs

I'm wondering if this is the right tool for the task I'm trying to do?

After spending the $6.50 or so for the rights to download the archive, I can't get it to work on my system. There aren't any instructions other than a sample command line.

I have the Barenaked Ladies 'Everything to Everyone' CD/DVD combo. The DVD "Everything else" has both the VIDEO_TS and AUDIO_TS folders. The audio includes both 24/96 surround and 24/96 stereo files. I would like to convert/decrypt to multichannel and stereo wav files and then I can encode to FLAC or WMA lossless to play from my computer.

At least the other tool, PPCMRipper, helps you generate to wav, but I couldn't get that to work either. I don't know what dvdcpxm.exe is suppose to create. When I run it -

C:\Rip\dvdcpxm.exe g:\audio_ts\ATS_01_1.AOB d:\barenaked

I get the following prompts:

Simple DVD-Audio AOB/VOB Decrypter

Processing media key block...
Unprotected media is loaded in drive g:
Nothing to do, exit!

This is after inserting the DVD in my DVD drive (G)

I'm bring this back to ask how the DVD files should appear on the disc with a drive that has CPRM.
Tried a CPRM disc I have in several computers. The ones that support CPRM don't see anything written on the DVD, whereas the ones that don't support CPRM show files on the disc, but because the drive doesn't support CPRM, they cannot be played.

I have tried this on 2 discs and I get the response that they are not protected - nothing to do..

Using DVDa Explorer to try and extract the tracks - it fails and says File Encrypted..

Is this a case where there is no CPRM but the watermark is tripping dvda explorer?

The watermark won't trip up DVDA Explorer. It doesn't know how to see the watermark in the data.

If you have a file \AUDIO_TS\DVDAUDIO.MKB then the disc is encrypted. If you don't have that file, DVDA Explorer should be able to copy tracks.

Just tried a new version of DVDA Explorer (alpha 8) and it worked fine on a encrypted disc that wouldn't copy with the previous DVDA Explorer..

So all we have to do is find some way to get past the watermarking..

[rasth]

Cool. I just grabbed the new version. Thanks for the heads up.

[keysersose]

A HUGE thanks from me!! - this new version is a very nice improvement and really simplifies things - much better than recording thru a soundcard and having to remake the MLP files and mucking around with cue sheets..

Ive just bought the LP Reanimation dvd-audio disc online and ive been trying to rip the stereo files off the disc but I cant get them off with dvdaudioexplorer, it says they are encrypted. I then try the dvdcpxm.exe and when I type the paths and filenames it doesnt do anything at the command line. it just keeps saying what it says when you type dvdcpxm,

Simple DVD-Audio AOB/VOB Decrypter

Use: src_file dest_directory

im typing it just like the example, but nothing happens outside of that. Any ideas?

Ive also tried following the guide at http://avisynth.org/mediawiki/DVDAGuide and ive tried the dvdfab but the latest version is much newer than the one listed and when i use it, it doesnt decrypt anything in the audio_ts folder, just gives a file copy error. So has anyone been able to successfully rip the stereo files off this disc? Thanks!

Could you give the full command line which you typed.

[rasth]

Try the newer GUI version. See the latest posts in the thread

You have to check off the box that says

Ignore Encrypted Stream

this will let you extract the stereo MLP files

When I do that it gives an error, MLP decoder failed during extraction when I have convert to wave selected. It will however extract the mlp file when store is selected.

The command line which I typed for dvdcpxm is

C:\Documents and Settings\Administrator\Desktop\adv>dvdcpxm L:\AUDIO_TS\ATS_01_1.AOB J:\New Folder

Edit: Ok, I made a folder on C: which is used in the command example in a previous post, C:\dvda_rip and now cpxm says theres nothing to do, on all the AOB's even though theres an .MKB file in the audio_ts folder. Now im really confused!

yeah I don't know why it wont extract the waves for you..

what is the reason for wanting the wave files?

you can make a new stereo DVD-A disc using discwelder..

I was just wanting to compare the 24bit to 16 bit files from the orignal Reanimation CD I have to see if I can tell any sound quality difference from my speakers.

Ive tried many different versions of dvdfab but most of them just gives the 103 error and stops immediately. One version goes up until 93% and stops at the audio_sv mpeg files with the same error.

I don't get it?

why not just compare the stereo DVD-A against the CD??

MLP is merely a lossless means of compression..so in theory is the same as playing 24 bit wave files..

Id rather just rip it to the computer with the rest of my collection. I use Foobar to play all the files back so its just easier for me that way.
