help backing up shark tale

[drisky9]

i'm trying to backup the disney shark tale game (u know what little boys are like with discs!) i've backed it up several times using different software but each time i'm just getting a black blank screen, the file size is only 1.26 so it's not burning much onto the dvd - could this have anything to do with it, but saying that i've been able to back up nemo and thats not much bigger but that works fine.

any help would be much appreciated
