Need help adding audio to a slideshow in iDVD. I don't see my playlists.

Question

I'm a relatively new Mac user & am trying to create my first DVD ever. I'm just learning as I go. I'm trying to create a slideshow with about 400 pictures to show at a "Going Away" Party. I've created a playlist to go along with it, but when I click on Audio & then on iTunes, it pulls up all of my songs in my whole library, but doesn't show my playlists anywhere. When I click on "help" it tells me that I should be able to go to Audio, click on iTunes, click on "library", & then find my playlist. However, I don't see "library" under iTunes. Help!

+but is it possible to make many different slideshows on the DVD but somehow have it play automatically from one to the other+
No. You can do that in DVD Studio Pro.
Here's a couple of examples of how I did these projects a couple of years ago:
*Mediterranean 2003 cruise*
I had over 1000 images from a Mediterranean cruise. I broke them down in to 24 Albums in iPhoto (fewer than 99 images each). In iDVD, I created 6 Folders which created sub-menus. Main Menu buttons (folders/slideshows) such as Barcelona, French Riviera, Florence, Rome, Naples, Malta. Then I added each of the corresponding 24 iPhoto Albums to those 6 slideshows, thereby creating 24 total slideshows on sub-menus. Takes some planning. All slideshows had transitions and music.
*Ireland 2004 iDVD Project*
Nearly 800 images dragged into iDVD as organized folders from the hard drive. Transitions on each image, and menus, sub-menus, and sub-sub menus. The sub-menus are created by clicking on the Folder icon on the iDVD interface.
Main Menu has 6 buttons: Downpatrick, Antrim Coast, Letterkenny, Sligo, Trim, and Extras. Behind each button are additional buttons ranging from 3 to 6 buttons. The Extras button goes fairly deep. When you click on Extras, it gives you 3 choices on a new menu. The "B&Bs" button opens a new menu with 5 buttons. The "Movies" button opens a new menu with 4 buttons. If you click on the "Irish Music" button, you open a new menu with 2 buttons. At that point, you are at a "sub-sub-sub menu."
Music was on most of the slideshows. Some movies converted to QT DV from Canon S400 digicam .AVI files (iDVD 4). Now convert to H.264 with QuickTime 7. Images are original 4MP (2MB) JPEG images from the same digicam. This DVD project is around 4GB with all pictures as DVD-ROM content.
