Ok..after using DVD fab and using DVD shrink there are data files there so the DVD can be burned. After burning a DVD using Nero I take the data files and put them on another Dvd and store it so I can burning a new DVD if the other gets damaged. When I try to put the files bakc on the computer there is an error MS-od error and it won't let me move the files to the computer. So now I have all these backed up data dvds and can't get them back on the computer to burn new DVD's.
