I went about it this way...

Download and install OSEx (http://www.macupdate.com/info.php/id/9830).

- Launch OSEx and insert the DVD. Make sure the correct title is selected by pressing the "Ti" button.

- Click "Vid" and deselect the video streams. Since you only want the audio, don't waste time with the video.

- Click "Aud" and select the 2 channel AC3 audio stream.

- Click "Fmt" and select "Elem. streams."

- Click "Seg" and select "Chapter" to split the audio by track in separate files.

- Click "Begin" and sit back.

After that is done, download and install mAC3dec (http://www.macupdate.com/info.php/id/10381). This program will decode the AC3 audio files and conver them into MP3 or several other file formats. I use the highest quality setting of 320kbps since I want it to be as close to the source as possible, but you can choose anything you want.

OSEx and mAC3dec are free programs, but I also use a shareware program called MP3 Trimmer (http://www.deepniner.net/mp3trimmer/) to give my project a more professional touch. In concert DVDs, when the tracks are separated, there will be a very jarring gap between the tracks and the shock of the applause starting and stopping can make it hard to listen to, so I use MP3 Trimmer to cut the sometimes lengthy applause from the beginning and end of the tracks, plus put a fade in and out so that they shock is less.

Yes, you can do the trimming from within iTunes, but not the fades. Plus, MP3 Trimmer does it without re-encoding the file and eliminates the resulting loss of audio quality. It costs all of $10.95, but has a non-crippled, non-timed demo. I have used it for several projects and been very pleaed, so I support the developer.

BTW, I am not affiliated with the developers in any way. I am just a happy user of their program.

A small tip that I learned from trial and error is that if two or three songs run right into another and you do not want to separate them at all, you can import them as one track so that the flow is not interrupted at all.

Using iTunes to split the files can be cumbersome. You have to know - timewise - where you want the splits to happen. What you do is highlight the song in iTunes, hit "Apple- I" and then "options" in the box. Then you input the start and stop times.

Big pain using iTunes for this.
