I was trying to back up a PS2 game but when I make the image it exceed 4.7 GB to be precise it was almost 8 GB. I told a friend about it and he told me that some of his pals can compress DVD games into CD, but they don't want to tell how. Is it possible to do that or were they lying? If it's possible, how can I do that? And also can I apply the same process to compress that image of 8 GB into a DVD disk?
