I got a message off this site that said that by removing the console cover of my Playstation 2 I would find two pins located undeneath the expansion bay (right about where the laser is). By turning the left one in (clockwise) I was to get a better response from the laser and no more "Error reading Grand Theft Auto: vice City DVD". It didn't work. However I removed the cover and then turned the left pin in about two more turns and the right pin in about one and a half turns and it worked way better with better picture. The pins are probably to adjust the angle of the laser. If the angle is off the Playstation cannot read the DVD correctly and you then get your error message. This seems to be the solution for the most common problem with the PS2. It would help if you have an O-scope to meauring the wavelength and angle of the laser for pinpoint accuracy. Hope to find more cool tips here and to provide more later.
