I don't understand people that always want to adjust the laser pot, even on a brand new PS2 unit. I prefer buying better media than messing with the already delicate ps2 laser. As for the azymuth adjust, it's a better idea since there is almost no way you could damage the PS2 by doing that. You can find the azymuth screw by opening the PS2 CD drive top, you can't really miss it.
