ripping high-res audio from Music Video Interactive (MVI) discs?

[TomCat2112]

Hello friends,

I am in desperate need of help. Years ago, I purchased a short-lived "MVI" format disc of Rush's Snakes and Arrows (2007). I've since parted with the actual disc, but I created an ISO of the disc before selling it. I can still *play* the ISO. I do so by "mounting" the disc using Virtual Clone Drive, and then I "open" the disc contents, and play the disc using an (.exe) application in the folder (a software called "Director MX 2004" - which I think was later acquired by Adobe). I love the sound of the high-res stereo tracks, and would like to burn them to WAV files. But I simply can't figure out how to do it. Let me explain.

I can see the "Video_TS" folder (there is no AUDIO_TS), so I have tried *many* software to extract the high-res audio from the video tracks (IFO/VOB) inside the mounted ISO file:
* DVD Audio Extractor
* DVD Decrypter
* VLC

What ends up happening is: the "extracted" files play back too fast, almost as though the sampling rate of the LPCM files is not recognized. I fact, within DVD Decrypter, if I mouse over the LPCM/2 channel stream to attempt to Demux, the stream is listed as: "0Ax1-Audio-LPCM-2Ch-Unknown(1)kHz/24 bit". I strongly suspect that the "unknown" component must be a hint to what I am doing wrong.

DVD Audio Extractor recognizes the (correct) track lengths - but when I try to rip them to FLAC, they come out to be 20% of their actual length, and playback is at hyper-speed.

Help! Any thoughts to what I am doing wrong? Has anyone successfully "cracked" an MVI disc previously?

Much appreciated,

Kevin

Since you no longer own the disc, you have no right to keep the backup you made.
