Hello, I have just received an imported version of Gran Turismo 4 which I bought off Ebay. My PS2 seems to have a real nightmare reading it, all is fine up until the intro movie but then it starts to skip and eventually pauses for very long periods (unwatchable). I also get pauses and long delays between menu screens and a couple of times I've had to eject and close tray for it to do something. Is this due to my laser being weak? (it's been fine in all games up until this point though) Any advice much appreciated. thanks.
