ok, so i replaced the laser in my ms25 drive today. figured it was needing one, as it would lock up occasionally on load screens, and was giving me a lot of dirty disc, disc unreadable errors. however, now it only loads a few of my burnt games. it doesnt have a problem loading origonal games, but wont load most of the burnt ones. all of the burnt ones were burnt using the same program, same burning speed, and all on verbs. ive attempted the rubber band trick, and hasnt helped all that much. before the RB trick, it would mainly get open tray errors. however with the RB in place, it recognizes that there is a disc in the drive, and will start to play it, but i imediatly get the disc unreadable error. any other ideas would be greatly appreciated.
