I found a website for someone in my area who installs mod chips in ps2's. I went over and he suggested the matrix modchip. He installed the chip, and apparently things went wrong (machine makes funny grinding type of noise when playing backups). He asked me to leave my ps2 with him so he can figure out the problem. The next day he called me up saying the chip was working the only thing is that it reads originals (DVD & PS2 games) fine, but when it comes to reading backed up games and movies it only seems to read backups made on pioneer discs! He said he has to do some fine adjustments on something to do with the laser so it can read all copies. Is this possible??? Please help me. Thanks a million in advance!
