The easiest way would be to use DVD Decrypter in IFO mode, with stream processing enabled, to extract the audio track you need.

Indeed, easy to do... But that's where I'm entering a new world that is all what I'd liked to avoid... I expected to have directly a AC3 or PCM file...

... Of course not. That leads to seek for another tool to convert the Vob to wav. isn't it ? Why did I felt it ?

Also I still don't know about what is made such a track of, if it is possible to remove SFX from it etc... Because if I convert a Vob to Wav, I guess it can't be anything else than a 2 stereo track.

Well... Does it really make a difference with the Microsoft Sound Recorder ?

Edit: ah... as far as I understand now watching the DVD Decrypter screen, looks like the AC3 as 6 Channels and the PCM as 2...

I even don't have a 5.1 plugin on my PC so you know !
