DVD sound Playback

On the topic of dvd playback.
Does anyone know how I can grab the sound stream? I've had a request 
to implement an equalizer in my dvd player, but I can't figure out 
how to get the sound stream separate of the video services.  Is this 
something that can be one with core audio, or is there some other 
library I can use for this purpose?
And, once I isolate the stream, are there any resources someone could 
point me to about applying changes to the realtime stream (more base, 
louder left/right channel and the like)?
Thanks in advance for any assistance.
