DVD plays out of order

Hi everyone. I am not sure if this is the right place to be. If not, maybe could steer me in the right direction. Here goes. I use dvdfab to backup movies that I purchase. This last one has me baffled. I send main movie to a folder, play it back and all seems just fine. Burn it to a blank dvd, it plays out of order. Not sure what to make of it. Tried 3 times, same result. Any ideas? Appreciate any thoughts on this matter.

Can you share with us the Movie Title, that could help us.

What version of DVDFab do you have loaded?
What burn engine do you use and what media do you use?

Again, what movie? What version of which DVDFab? Have to have something to go on to get answers.
