Help with slideshow

I am new to this forum so thank you for any help or advice! I am using Nero 9 - I am trying to turn my vacation photos into a slideshow and burn them to a DVD to watch on my TV. I made the slideshow, but I am unsure of what to do next. ANY help would be greatly appreciated!! Sorry if this is such a basic question.

You should just hit the next button into the lower right corner until the burn screen appears. Insert a blank disc, check to see what drive Nero is going to burn to, and then hit burn.

Do you need to save the slideshow as a movie first? Or just burn it to the DVD?

What is export? AVI, MPEG?

Thank you for such a quick response. I REALLY appreciate your help!
