Can AnyDVD back-up DVD-A's and remove their encryption?

[quicksrt]

Pretty sure an Oppo 203 flags the watermark in al DVD-As.

The discs that I have which were de-watermarked sound spectacular on their own. But I'd not compared the originals with these revised files. And the audio files (complete title) needed to be reauthored and so original disc menus were of course gone. A couple of members here were involved in this research study. The main hacker-crack has not been seen since Dec 2023. I hope he returns to contribute, a long time member here.

I will note that we have by now answered in full the subject of this thread - AnyDVD can backup some DVD-A’s and remove their digital (CSS?) encryption, but not all (evidently not CPPM in at least the cases I tested). Those disks that worked in AnyDVD for me are DTS, Dolby 5.1, or Dolby AC3 not MLP and so do not have AUDIO_TS content, and those particular disks do not have audio watermarks (and so those ISO rips should work in hardware players). It may be appropriate to move further discussions to a different thread or new thread.

OK. When I have some spare time later I will refresh my memory on the details of how to temporarily reverse the Oppo jailbreak and will check on whether individual watermarked tracks trigger the watermark detection. If not I might be able to author a DVD-R with a few extracted and converted tracks and test. Since I don’t have an MLP encoder that can produce 5.1 MLP files I can’t really test a bona fide DVD-A that I have authored and burned.

The only DVD-A images in my possession are rips of physical DVD-A’s that I own, or images with MLPs produced from conversions of Q4/Q8/QS/SQ/CD-4 analog media. Obviously the second type are not watermarked.

I can tell you right now that the watermark is running thorough the entire track(s), and comps will not play either. I think Jon actually made a disc of tracks, might have converted to DTS and burned to disc for the car and hit a road block there as well. It was and is a very persistent protection.

Yes. Again, read the USENIX paper. The watermarks are robust, occur every 6 seconds or so in all of the 5.1 tracks (see the console in foobar2000 with detection enabled), and survive any sort of conversion, including lossy compression, that does not alter the particular analog audio encoding. They even survive conversion to analog by recording audio played through your sound system with a microphone (presumably a high quality mic and recorder, since why else bother).

As you can read in the USENIX paper from 2001 that I linked above, those researchers had been able to alter the watermarked samples (in 1999 I believe) such that the watermark was no longer detected. It's long been known how the watermark works, and as with the very similar Cinavia watermark, how to alter the analog audio to disable its detection. The important question has always been whether "golden ears" can detect the audio manipulation necessary.

In foobar2000, you need the "foo_dsp_neutralizer" plug-in. This is a DSP plug-in that is only packaged as a .dll that you have to manually put into the components\ subfolder, as it is not provided as a .f2k component (i.e., you can't use the Preferences/Component/Install process from within foobar2000 itself). It's an old plug-in, from about 2011 IIRC. The README has a ton of caveats:



I've not tried this neutralizer but can certainly do so and report back whether the foobar2000 watermark detector indicates success.

It has never worked for me. There is a certain way to set it and a bit of luck involved or so I have been told by a guy is has been successful with it many times. Some discs are reported to be more difficult than others or not done at all.

The DSP neutralizer and method have been known for years. It was asked at the time it not be posted on the forum so as not to rile the recording industry folks. So while I've never needed it, I've continued to honor that.

Apologies. I've edited my posts and redacted the info. Since I have no need of it either, I'll drop out of further discussion.

Just an FYI. I pulled out an old burned copy of ELP's Brain Salad Surgery, which is definitely watermarked, and it played all the way through on my OPPO UDP205. I guess OPPO figured DVD-A was a defunct format and saw no reason to include watermark detection in the 20x series.

So my question has been confirmed...

Nobody has managed to create software that's able to remove encryption from a DVD-A disc prior to creating an .iso file. What a shame. I was hoping to keep the discs original file and folder structure intact

I have no idea how any of it is viewed now, to be honest. But I've spoken openly about using DVDFab, so there's that.

Being inspired by the new Alanis Morissette "Jagged Little Pill" Blu-ray disc, I thought that I would revisit the DVD-Audio of "Under Rug Swept". I tried to rip the disc using the combination AnyDVD HD and DVD Audio Extractor. It did not work, the program started "spinning" and eventually popped up a message that the program is not responding.

I haven't tried to rip any DVD-Audios in a long while, but I do remember that some were seemingly "impossible" to do so. Reading here reminded me about DVD-Audio Explorer. It appears that development stopped in 2008. I'm running the 2008.7.21 Beta 3 version, seemingly the only version still available. I don't see any option to save as an iso. but It did work to rip the disc to tracks. Saving to tracks is what I prefer to do anyway, although I do see the value in saving disc's as isos to retain all of its features.

The odd thing is that the tracks were ripped with C and LFE done as a stereo wav file. The other tracks L, R, Ls and Rs were saved to a separate 4.0 wav file. To be useable I had to open all the files in the multitrack view of Adobe Audition 3. Then using the Surround Encoder was able to create a more normal 5.1 wav file. It is rather time consuming as the process has to be repeated for each track.

I never thought that "Under Rug Swept" was a very good surround mix and noticed that on some tracks at least the front channels, if not brickwalled were very heavily compressed. It was an easy job to run those compressed files through the VST plug-in Relife. Looking at the waveform before and after it is making a huge improvement. Sometimes with very heavily brickwalled sources Relife doesn't do a whole lot but on this disc there was still something to work with. It's still not a great surround mix but sounds quite a bit better after my tinkering.

I evidently was able to rip "Under Rug Swept" DVDA as an .iso, or either decrypt somehow the folders and reassemble as an .iso.
Anyway I no longer have the disc, but have the .iso rip.
I suspect I ripped with an early version of DVDFab, though no way to verify now.

I should have read the DVD-Audio Explorer "User Manual" first. Instead of ripping to the rather pointless Stereo C, LFE file + Quad L,R,Ls and Rs file combination you can select to "Merge" them into one 6 channel file or to "Split" into separate mono wav files. The manual even states that the first (unchecked) option is not likely what you would want!

I just ripped Faith Hill "Cry" using DVD-Audio Extractor without the help of AnyDVD HD and it worked fine. I wonder if AnyDVD interfered with my attempted ripping of "Under Rug Swept" yesterday?

Another point is that the files Ls (left surround) and Rs (Right surround) are the same as BL (back left) and BR (back right). Rhino is encoding the back (surround) channels as SL (side left) and SR (side right) on the Quadio Blu-ray releases. I don't know what caused that change of standard but it's one way to create unnecessary compatibility issues!

You can also save as mlp files, IIRC. Haven't used it in years.

It seems like Redfox AnyDVD may have been shut down. Their website is inaccessible (has been for days), and the software can no longer decrypt Blu-ray discs. It gives an error that is was unable to connect to the server where it gets the hash keys from, and the decryption fails. Bummer.

 

[mandrix]

I recently successfully ripped a DVDA with DVDFab. No problems I could see.

When you ripped the DVD-A disc with DVDFab, did it remove the watermark? I think that was mostly Rhino's first batches of those discs when the format first arrived. The only way I have dealt with it is rip it and then convert the wav files to DTS to burn to 5.1 CD

Yea - I found this out yesterday when I was going to rip the blu ray of Robin Trower "Bridges of Sighs". I also went to the Redfox website on my laptop and iphone and - it can't be found, unable to connect to server. Now need new software to decrypt blu rays for ripping (for personal use). Any suggestions?

REO Speedwagon - LIVE plus was the test disc.
I don't know how to test it as my disc players will ignore the watermark.
The rip was just to prove that DVDFab will rip DVDA. Beyond that I have no idea.

I just used MakeMKV on "Bridge of Sighs" followed by ImgBurn to make an ISO file. Slower than AnyDVD, but functional.
