I just got my modchip installed today, my playstation is V9 or V10, i'm not sure exactly though. I don't see a big difference otherwise I would check to see what version it was. I copied 3 games, all using nero with the same method as sticky thread has. 1/3 games work, and I have no idea why. I did the same thing for all of them, yet only 1 works. My playstation won't even read the other two, it just stays on "Reading disc..." and it sounds like it's having trouble reading them. I'm not sure why this is happening.

Also, should I get DVD-RW's or DVD-R's? Would it make a difference?
