Sorry i should have said that on my psx I use one of those swap cd's also have a plug mod, the games work with either one.On my old psx I had same prob. as you, found on newer one (not a psone) and all my back-ups work better, I think it was because the lazer was old and to worn out for cd-r, if you clean your lazer and still have prob., you might need a newer system.Better yet a chipped ps2.
