I don't have Aperture so try it's help menu with the term DVD, it may
give clues to a way to burn as a standard DVD slideshow from Aperture.
Otherwise try opening Toast & selecting Video > DVD-Video from the
types of disk available to burn, then drag the pictures into the main
Toast window. Tweak the various options to alter the names & times etc
& it should burn to a DVD-R that has a Video_TS folder.
You can also ask Toast to make a disk image to test without wasting a
DVD, just open the disk image afterwards & try playing it back in DVD
Player on the Mac, you may need to do File > Open… & select the
Video_TS folder on the mounted image (post back if this is unclear).
Standard DVD slideshows use still images (potentially with crappy
transitions) so you may want to use iMovie/ iDVD or iPhoto to make
video versions if you need movement/ better transitions on the slides.
It will turn them into video files, not the greatest for keeping
quality on images.
Aperture may have an option to integrate with the iLife suite
depending on what versions you have. This means you can pick Aperture
files from within iPhoto & iDVD easily. Turn on the 'Share previews
with iLife & iWork' in Apertures prefs.
