Only one iTunes song plays during DVD slideshow

Question

I have built a slideshow in iDVD6 that's about fifteen minutes long. I added four purchased iTunes tracks, grouped in a playlist, into the audio well in iDVD. The Project Info shows the four tracks.
Only one track plays, however, on the burned DVDs. It repeats itself several times until the slideshow is finished.
In reading other posts about audio, I've noticed that too little available space on the drive with the project can sometimes make iDVD a bit wonky.
I have about 15 gigs available - could that be causing this problem?

Answer 1

15GB should be sufficient, although more always is better.
On the chance that some preference or permission is corrupted, try the following standard stuff that we do when an iLife program is acting weird: Close iDVD and trash the file com.apple.iDVD.plist found in User/Library/Preferences. Then do a permissions repair using the Disk Utility app on your Mac.
If that doesn't solve it, as a workaround you could try joining the songs in your playlist into one total soundtrack. You could do this by putting your playlist into an iMovie project and then exporting your playlist onto your desk top as an aiff file. (File/Export/Expert Settings/Share/Sound to aiff) Then import that file directly into your iDVD project, or into iTunes and from there into your iDVD project.
Another way is to export your playlist to a musical CD, and then import all the songs at once from the CD back into iTunes, checking the "Join CD tracks" option on the iTunes Advanced menu. That will join all the tracks into one long clip.
Perhaps someone else will come up with a better suggestion. Good luck with this.
