Need help with PS2 backup

[Senji]

I'm having trouble making a back-up for God of War on PS2. My PS2 is moded and I have a DVD burner so normally when I back-up PS2 discs I just use nero - copy disc and I'm able to make workable back-ups without any dramas.

However when I tried to back-up this game I had trouble reading the disc with Nero. So instead I copied all the files on the dvd onto my computer in a temporary folder. I was just wandering how can I make a PS2 formated disc using these files??

I tried searching online for information on it but there's is such a wealth of information on ripping etc that I wasn't able to find exactly what I was looking for.

Any help on this will be largely appreciated.
