I used to use Adobe Premeire, but recently have run across this little program: Potodex Proshow Gold
. Not too shabby... lots of options, templates, add, soundtracks, motion, easy to use. You can output your slideshow to a vid file, DVD, screensaver, stand-alone executable file... etc. What took me half an hour to do on Premeire and render takes me about ten minutes to do now. But I'm sure in about a couple of hours, there's gonna be something better. For now, I'd recommend it.
PM me and I'll try and email you a small sample of what I put together with it.
