<< try toothpaste not the clear kind. >>
I'll concur. I pulled my DC off the entertainment center one day, scratched my Residernt Evil : CV disk in one spot, abou 3/4" of an inch long. I took a little toothpaste , put it on a soft cloth, and wiped from the inside of the GD-Rom out. I followed it with a damp cloth, then a dry one, repeating that process until it read in my DC.
