I've searched and could not find an answer for my question. I have a ps2 with usb modchip (the one with on/off switch) installed for my boys a couple of years ago. We're having problems playing the DVD-R backups and after reading this forum, I'm beginning to see there are better ways to do this (better chips). I would like to know if it's possible to change the chip and does anyone know where I could get this done? Thanks. Much appreciated.
