Im trying to back up this game. When I check the disk properties of the game it says it is 621mb but when i try and copy the disk, the image file read and created is 714mb making it too big to burn successfully. Im using Nero 5.0 with settings as per recommended on GameCopyWorld site. Ive had no problems with any other backups and would really appreciate any advice as to what is going on and how to remedy it.
