[jesus is my pimp]

I've been trying to recopy UFC onto another disk and have not been able to do it. I've tried to use the PSX Copy 6.2, CloneCD, and DiscJuggler 2.0 and none have worked. The copy of UFC I have works prefectly, but I just can't make a copy of the one I have. I have already make successful copies of Marvel vs. Capcom and Crazy Taxi. Any suggestions? In case it helps, I'm using a generic Compaq 4x CDR.
