NTI CD/DVD Maker Gold ripping & burning problem

This program came with my computer, and I wouldn't use it if I could avoid it. I'm trying to backup my Seinfeld DVDs, and DVD Shrink won't read most of them for some reason. NTI does read them and copies them to an image file for burning to DVDR. All my Seinfeld DVDs are small enough to fit on a corresponding DVDR without compression. However, when I rip a DVD with over 2GB of information, NTI breaks it up into separate image files of 2GB each. When I try to burn them to DVDR, it will only let me choose one at a time. With a DVD+R, I have to burn them both at the same time or else use two DVDRs. Anybody know how I can get this stupid program to either stop breaking the image file or to burn multiple image files?
