You can create Slideshows directly in Aperture; there are several predefined themes. Arrange the images in the Time Line, drag music from the Media Browser into the timeline, press the "export" button and render a movie (this step will take some time - be prepared to wait for an hour or longer, if the slideshow has many effects). See this section in the Aperture User Manual on how to create Slideshows (Creating Slideshow Presentations).
You can play the exported movie on your mac, but to burn a video DVD to be viewed in a video player, you will need additional software, for example iDVD or Toast, see this User Tip by Karsten Schlüter:
