M Master, if you may please name those ripping softwares; I have been trying to do those move too. I know that CEP can rip the audio part of a vcd but dvd, 'am lost.
I've used DVD Audio Extractor. It works just fine. It allows you to extract either a stereo or 5.1 surround mix. Haven't had any complaints. When you open a DVD with it, it shows you all the chapters, and has audio preview function.
