Depending on what you tell us about your computer (in answer to the request for more details) it may be possible to directly answer you question but my suspicion is that 40 minutes to produce a slide show of 2.2Gb (how are you measuring that, by the way?) is not too long.

PS. You will see I have moved your post to the Photo & Graphics forum where it is mor elikely to be seen by other users of the specific software.
Hello! I have traveled to many countries, and for several years I have used Photostory Deluxe to produce numerous slide shows of my pictures from around the globe. I burn them onto a DVD. Would someone be able to tell me if it is possible to make other copies of my existing slide shows from my DVD unto another blank DVD? If I can, then would someone be able to tell me how I could accomplish my objective. Thanks
Your question really has nothing to do with the content of this thread, which is about how long it should take to burn a rather large project to DVD; I would strongly suggest you begin a new thread with your question.
Essentially, yes it can be done, if you have suitable software available.
