yes there are, plenty of them just go to http://www.download.com and search for dvd audio and you will find tons of programs but most being free trials, i use dvd audio extractor(forget which one it is the one that lets you preview the audio only before extracting).
there are plenty of ways to rip the audio from a movie as jondrew says but if your after a track thats on the movie and you dont want any interference from actors talking over it youd be better off just finding out the name of the track and downloading it from somewhere like soulseek or something
