I have a DVD with a VOB file of 3443 MB. I can't use the application I have to dupe it because the destination DVD only holds 700 MB. How do I duplicate the VOB file to another DVD using the same amount of space?
The destination shows the size of a CD and not a DVD disc. This means that you should insert a DVD (4.7 GB storage) and then perform the dupe which you'll see it will work.
