Hi Kathleen, The following might help:- Prior to exporting from iMovie to iDVD ensure the magnification in your Timeline Viewer at the bottom of the screen is set at "1x" and not "Auto (20x)". I sometimes need to leave the Player Head at the RH end of the Timeline Viewer to retain the setting when I give the command to "Export". Checking the resultant QT movie in QT Player will show whether the sound is broken up, or not. I seem to have only encountered this problem since upgrading to OS X 10.2. Earlier on I did not have to worry about what magnification setting I left the Timeline Viewer on. Ian Tucker
