I got around the problem by leaving it on the Full Disc screen, picked ISO as the target touched nothing else. Clicked on start. Closed Fab after the copy completed. Opened Fab back up, Left screen alone again, picked the ISO as source and Fab temp folder from the drop down box as target, and clicked on start and nothing else. After that completed I closed down Fab and used ICopyDVDs2 to copy and burn. Worked Fine for me. It may work with other burn software.
The problem may have been that the movie had a web link at the start that needed to be exited to view the movie.
