hi i have a playstation ( 9001 ) and i backup games ... well currently ive been burning onto precision and verbatim media and the last 2 games ive had got errors while burning ( the games were spiderman and final fantasy 8 [ the 1st disc ] ) and when i play the game in my psx on the first movie of both games it locks up ( by the way the error said cd read failed ) .. is this happening because of the copy or because of the psx ...

ps. the original doesnt lock up in my psx

? thanks
