How can I export slideshows created in Aperture v3.3.2 from Mid-2009 MacBook Pro-17 to blank DVDs?

Question

(Fifth futile attempt in two hours, before I learned there was a Post webpage – I’m new to ApSuppCom - and after I learned that I am not allowed to update previous content, so I had to back out, make a few changes, and start over.)  How can I export slideshows created in Aperture v3.3.2 (complete with superimposed captions and music tracks) from Mid-2009 MacBook Pro-17 to blank DVDs ?  (Some other specs: Mac OS Lion 10.7.5; Capacity 499.5 GB;  Processor 2.8 GHz Intel Core  2 Duo; Memory 4GB 1067 MHz DDR3; Graphics NVIDIA GeForce 9400M 256MB)
I cannot do a copy (export) without various error messages appearing and the inevitable stoppage occurring.  Always with the DVD Video Player final message reading, “Supported disc not available.” Advisors and Mac Geniuses at local Apple Stores have told me to try Roxio Toast.  When I visited the Roxio website, and found numerous other company products, the descriptions all seemed to suggest that most of the apps shown can easily export videos to DVDs, but nothing was said about finished digital slide shows being exported.  At future events soon,  I hope to be handing out these finished DVDs (free) to the people in them.   Any help will be greatly appreciated.

Aperture cannot burn slideshows to a DVD.  It only can export a video of your slideshow.
In Aperture 3 you use the "Export" button in Aperture's slideshow project to render a video to a folder on your disk.
Then you use iDVD or another program to burn a video DVD.

Could you please describe the exact steps that are causing these error messages?
How are you exporting your slideshow from Aperture? Which settings are you using? And how are you importing the video to iDVD or Toast to burn a video DVD?
