No audio on video in iDVD

I just got a MacBook and am trying to turn some old miniDV tapes into DVD's. I used iMovie to get the movie off of my miniDV camcorder with a firewire cable. Then I used iMovie to do a little editing and clicked Share>iDVD. It transferred the movie to iDVD without any trouble, it had the chapters and I added a slideshow. When I burned the final iDVD project to disk, the audio during the movie is gone. The songs I added to the menus and the slideshow are fine, but there is no sound during the movie that came from iMovie. What am I doing wrong?

find out if you need to extract the audio

I don't know if this makes a differences or not, but I don't export/share my movie. I just open up iDVD an import the move from iMovie. I just locate the iMovie project file and it reads it in. As for extracting the sound, I don't think you need too.

Also I assume that when you share/export the movie you hear the sound in the quicktime movie file, when you play it?

Everything runs fine when I test the playback of the completed thing in iDVD. hmmm

do you mean you can hear the audio in idvd, have you tried it on a tv? anyone know how idvd compresses the audio for a dvd?

Well the dvd wouldnt even play on my tv dvd player but that could be just that my dvd player has a lot of problems so im not concerned about that. But the dvd is lacking the movie audio when i play it on the computer in 'dvd player' and when I burned the project to a disk image it had the same problem.
