iMovie Soundtrack

Hi,

I am working on a DVD and wanted to drop some music and replace it by a different sound.

All of a sudden the new music won't play, not give a sound. I have gone through everything, compared and cannot find the failure. The music plays perfect in iTunes, or in the music selection in iMovie; but as soon as I drag it to the Project it s mute.

The bar that indicateds the soundlevel remains black.

Can anyone help me again, please! I am really stuck.

THLMUC
