I am trying to back up a software DVD-Rom with approx 5gb of data on it. It is a program, not a video. As I have backed up DVD movies with more than 4.4gb using DVD Shrink and Decrypter, I have never tried to do such with a DVD-Rom program. Has anyone had any luck with this as far as splitting the program to 2 SL discs? If so, which software seemed to do a good job? Or am I stuck with putting it on a DL disc? Thanks for your help and patience.
