Idvd won't load playlist

When you click on the little triangle next to the iTunes item in the media audio pane, you should get a drop down that shows all of your play lists. When you click on the play list's name the songs in it will appear at the bottom of the pane. You need to put your cursor on the dot at the top of the play list pane and pull up on it to reveal the pane. If you are still having trouble it might be because your songs are stored in the cloud and have not been downloaded to the iTunes library.
