@gp2221,

There is an open source decrypter since a while:

Are you referring to the open-source CPRM/CPPM decrypting library and sample decrypting tool - dvdcpxm.exe?

Have you used this tool? 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. Or, I might be using the wrong tool.

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.

Yes, i decrypted all my (six) DVD-Audio discs with this tool.

Too bad, it's possible to download it for free. I guess you clicked on "premium" instead of "free".

That means that there is no encryption on the disc

Just copy the AOB files to your hdd, and use DVDAExplorer_a7.exe to demux the audio streams.

I wrote a guide on this stuff a while ago:

Thanks for the guide, it was very helpful. I see how to demux the audio streams into MLP, but the trick now is to decode the MLP into WAV. From there I was planning to encode to either WMA lossless or FLAC. However, it looks like you have to use a couple of tools that are fairly expensive -

1.The Sonic filters "Sonic HD Demuxer" and "Sonic Cinemaster@Audio Decoder 4.3.0"
2.Surcode MLP

I can't find the Sonic filters and can't afford the Surcode MLP encoder. There is a Surcode MLP demo version that does not encode. Will this version generate WAVs?

There is an open source MLP decoder since a short while which can be used within AviSynth:

http://forum.doom9.org/showthread.ph...19#post1064419 (read also the posts after this for how you should use this in AviSynth)

Note that your audio will be downsampled to 16 bit (which is a restriction of ffmpeg) when using this decoder.

Yes, that guide is a bit outdated, but i would like to wait with updating until this MLP decoder is integrated in ffmpeg (they are still fixing bugs ...).

This is when I try using an mlp file that was created by an extraction from DVD-Audio Explorer. It might have something to do with the channel order. It looks like my mlp file is using this channel order:

ID 20: Group 1 (Lf, Rf, Ls, Rs), Group 2 (C, LFE)

and I'm not sure if eac3to can work with this.

I also don't know if I need to install a bunch of new decoders or if they are included with the zip file. Anyhow, it looks like I've got a lot of reading to do. Thanks for the link. Any advice for making this work is much appreciated.

I was hoping to maintain the bitdepth of 24 bit. Do you know if they are working on a version of ffmpeg that will not alter the bitdepth?

It should be possible to wrap it into 32 bit using some settings, but we were unlucky getting this to work. Perhaps it will work when they have added the MLP decoder to ffmpeg (which can happen any moment).

I used your guide "DVDAGuide" for a dvd-audio with watermarked.
I got 3 wavfiles now.
test_clfe.wav
test_lfrf.wav
test_lsrs.wav
Is it possible to extract those 3 files, so that
I get in the end 5 high quality mono wav files?

Sure. Use Wavewizard, AviSynth, etc ... (Besweet doesn't support 24 bit output). Using AviSynth:
Code:
v = Blankclip()
a = WavSource("D:\test_clfe.wav")
AudioDub(v,a).GetChannel(1) # first channel (c)
Open the script in VDub and extract the WAV (File -> Save WAV).

Thanks.
Got now 6 mono waves.
Made from that a mlp with surcode, and again with disk welder
a dvd-audio.
But on a standaloneplayer again after 10 sec finished.

I don't understand that powerdvd is playing the dvd-audio
without any problem. Even the HQ part.
Is there perhaps a way to stream the output from powerdvd?

Not any version of PowerDVD has watermark detector. Check "C:\Program Files\CyberLink\PowerDVD\AudioFilter" folder. If it does contain CLAud_w.ax file then detector is here, if it's just CLAud.ax then no detector.

I check it.
It has just CLAud.ax so no detector.
Good to know. Thanks.

I have CLAud_w.ax. Does that mean I need to downgrade PowerDVD to an earlier version in order to play burned watermarked DVD-As?

(which wouldn't bother me in the slightest)

No, that doesn't. Detector was included in some rather old versions of PowerDVD (like 7.0.2602), then disappeared. I'm not sure about the latest one, but you can try to upgrade as well.
