I dont know if this would be of any interest but thought to share it with you all anyhow.
Ripping audio i.e MP3 or Wav is not that difficult, loads of applications available, but yes ripping the Dolby 5.1 Track sometimes can be tricky particularly with virtual Dub. And yes an audio music track on 5.1 Dolby does sound amazing. I use VirtualDub MOD for this purpose though it rips all formatts of audio tracks but here we will see how to rip a 5.1 Dolby track off a Vob(DVD Video) file.
Download Virtual Dub from below link .....(believe me Vdub is an AWSOME, Fantastic tool if you know how to play with it, it does a lot; A LOT more then what we are discuessing here)

STEP 1 : Run Vdub ofcourse....
STEP 2 : Open the video file VOB that contains the song to be ripped from the DVD loaded or ripped
STEP 3 : If the file has multiple audio streams, choose english (usually its the first one)
File would be loaded
STEP 4 : Drag the slider bar at the bottom till the point from where you want your song/Audio to be ripped.
STEP 5 : Click on the mark in tab to select the initiall point (thats the second last tab at the bottom). Now drag the slider bar to the point where your audio/song is ending
STEP 6 : Click on the mark out tab to select the final point (thats the last tab)
STEP 7 : Click on Stream and then stream list........(This step is the Tricky one, which is difficult to figure out)
STEP 8 : You would be shown the audio stream you selected at the begining.
Right click on the audio stream and make sure that "Direct stream copy" is selected(Which already is......by default BTW)
STEP 9 : Hit the DEMUX button and you will be asked to save the destination file. Give the name and file will be saved. It took take less than 3-5 secs for a 5 minutes song to be ripped on a C2D @ 3.3Ghz.....just a benchmark...
FINISH you have the file in AC3 format with full 5.1 Digital Dolby Track.
VDub can also rip in wav/MP3. A similar tutorial is been uploaded in DOC format incase people need. Following is the link...

Also the reasult file which I just ripped is there for you to listen. Its a small clip of a song from movie iRobot called "baby superstition". Great Dolby 5.1 effects you can test with the song.
