I have a single layer dvd I wanted to back up. I extracted with DVD Descryptor to an ISO file. Then burned. There was a problem with between Chapter 16 and 17 freezing. I then made a new ISO with DVD Shrink and same thing. Finally, I used DVD Shrink to extract and burn at the same time, NO ISO and the copy is flawless.
What causes some ISO’s not to work?
