PPT 2004 for the MAC and audio files

I have created an 85 slide (30 MG) PowerPoint presentation (MAC 2004) with 28 video clips included and heavy animation (32 minutes). Since the Narration function in this program does not work with a file of this size, I have tried Audacity and several other audio programs but am unable to get audio to sync with existing PowerPoint slides.  The slides change their rehearsed timings or the audio files change theirs. [I also have iMAC and G5 in my office.]

I am fairly expert at PPT and have created many presentations for clients for many years.  However, I have never incorporated an audio file with a presentation of this size.  When finished I need to get the combo slide/audio presentation on DVD.

Using the Quicktime Movie approach did not work either.  PPT would not work in iWORKS.

Is there an easy way to do this?
