I noticed that DVDFab creates a configuration file when I do a DVD to DVD rip using Clone. I use Windows Image Burner to burn the ISO I created. Does Windows Image Burner use this configuration file? Does any program use it? I noticed it contains the info for the layer break when doing DVD-DL discs (also DVD-+R, but there is no break). Is the info contained in the ISO? Do I need this file at all? THANKS!
