Some videos have various audio options. Some are not required. For music vid's, if you have the choice b/w pcm (= aiff) & ac3 then ac3 will take up much less space ... but just make sure that taking one out doesn't affect some particular section of the vid. The sample below is not pcm but mpeg audio but was the only example I could find handy at my fingertips. (as a side-note mpeg audio is only available on pal dvd. yipee!)
I almost always encode using ac3 audio so I can maximise the space available for video. I create lots of videos from full quality video.
