Laser damages

[filliper]

I would like to buy it... I have a US PS2 V3.... I can't get the messiah so I thought about the NEO chip.... but my PS2 already have a chip installed... i don't know the model of the chip I have... I think it's the first modchip released for the console... i can't play any game for it without swap including PSX... I can't play DVDR... and now I'm worried about my laser unit.... I never played DVDr on it... I played some PS2CDR and PS2 DVD original without problem...
