Burning Keynote presentations in iDVD
When you export a Keynote presentation (one that contains audio) as a QuickTime movie and then try to burn it to a disc using iDVD, the audio won't be on the resulting disc. This happens because a Keynote QuickTime export produces two separate files:
title.mov
title_soundtrack.mov
The title.mov file must reference the title_soundtrack.mov file to play the audio in QuickTime Player. However, this reference is lost when the title_soundtrack.mov isn't imported.
To keep the audio intact when burning a DVD:
Import both of the exported .mov files into iMovie, and drag them to the Timeline.
In the Timeline, trim the audio to the video track.
In iMovie's iDVD pane, click the "Create iDVD Project" button.
In iDVD, burn your project.
This can occur with Keynote versions 1 and 2 and with all versions of iMovie and iDVD.
