Does iDVD allow you to specify video and audio from two files? If so, then you can save the audio out to a different format, like AAC and then combine it at authoring time.

I wish VLC would have more solidly identified the audio, instead of saying later 1 2 or 3. Quicktime (even with Perian) seems to only like layer 3. I wonder if the MPEG 2 components for Quicktime widen that support.

iDVD won't let you specify a separate video and audio track, but iMovie will. Workflow would be to import into iMovie the separate audio and video parts, then hit the export to iDVD option.
