[T.D.K]

I'm trying to make a backup of my copy of Test Drive. It's a DVD game and takes up almost 4gig. I'm using Nero and I've tried a direct copy and imaging then burning. It burns just fine with no errors but will not boot on the PS2. When I try, it appears to begin to load (PS2 splash comes up) then goes to a black screen and just sits there.

I've got a Magic31 chip installed and haven't had any problems backing up any of my other DVD games. I'm assuming it's something Atari has done to prevent playing a backup, but I have no idea how to fix it.

Any suggestions anyone?
