I just got my ps2 modded. It plays pretty much everything: backup dvd-r ps2, ps2 games, dvd movies, backup dvd movies, psx games. The only thing it can't read is backup psx games. I've tried cleaning the laser, readjusting the tray, etc. Should I try readjusting the laser or is the problem with the laser itself?? Thx to anyone that is willing to help.
