Idvd And Imovie



When I burn a DVD from iDVD the sound is not burned as part of the transfer. The movie is transferred but the sound is not.

What am I doing wrong that does not allow the sound to be transferred.

The sound is a song from iTunes.

When I play the movie in iMovie or in iDVD both the sound and the movie come out.

But the sound does not transfer during the DVD burn
