Photo to Music is a very good slideshow application that lets you do considerable amount of customizing of transitions, KB effect, adding titles, music etc.

I've read about converting Keynote presentations to Quicktime and adding to iDVD but haven't tried it myself. For real pizzaz you might look at PhotoPresenter. You can download and run it in demo mode to see if it could work for you. You would add your music before the slideshow you want it to play with, then the slides, more music, more slides, etc. it has over 25 themes of which these are two: Apple TV Intro and Reflection. It may be a little too much fluff for your situation but they do show well.

Have you tried Keynote.

That's a PC application. Do they have a Mac version somewhere on their site? I couldn't find it. Or are you going to run it on a PC?

have you looked at Adobe Acrobat Professional? it will do a slide show with transitions and music can be added. file sizes can be kept to reasonable size plus the ability to play on any computer with acrbat reader installed
