Isolating the Audio Track from a DVD

Hi,
I've tried a variety of searches on this topic and have yet to find a post that clearly answers my question.

I am trying to isolate the audio track from a DVD I own and then use that file to create several ringtones and sound effects for my iphone. I am planning on using garageband to create the ringtones but am a bit confused about which program would be best to use to rip the initial audio track. From what I have read on the forums so far, there appear to be several programs that can do this but I am looking for some clarification.

Which program would be best to use? VLC, MPEG Streamclip? FFMPEGX? Any help would be greatly appreciated.

Your best et is to play the movie in DVD player, after hijacking the application using Audio Hijack

Thank you for the advice. Being a poor grad student, I had to search around a bit for some freeware programs that could accomplish this task. What I ended up doing was using MPEG Streamclip which was able to export the audio of the DVD directly into an aiff format from which point I was able to cut up the sound bites I needed using Audacity. Thought this info might be useful to others with the same problem.
