error reading disc.....

[shawn]

I have a V4 PS2 that's in very good condition. Recently, I installed a no solder mod chip in the system. I just burnt Vice City, and attempted to load the game. I am using Action Replay 2. I successfully loaded the game and began to play it. Shortly after my first mission, I was driving down the street and the game stopped, and white text on the bottom of the screen read "error reading disc......" not exactly sure what it said. I ejected and put in the original, and was able to resume play from there. I do know that the original I copied was pretty scratched up, but it had no problems copying. I am using Ritek DVD's (not the 4x ones). Any advice?
