Help with iDVD

Creating a short, looping slideshow in iPhoto. When played in iPhoto, slideshow loops fine—the last slide smoothly fades into first. When I play in QT or export the slideshow through iDVD, the last slide fades to black and then returns to first slide. I've tried unchecking "none" in the transitions drop-down menu, but no luck. Anyone know how to remove this annoying black fade at the end?

Thanks
