I don't use the software mentioned but what are you actually doing. Direct DVD to DVD copy or making an ISO image. Looking at the error it's a read error, so it looks like some form of protection has been reached and the software is unable to recover. If that's the case and a DVD to DVD is being attempted, you end up with a coaster. On the other hand if you're creating an ISO image you just need to find a means of bypassing the prtection to create the image, then burn that to DVD.
