Adventures In Repairing DVD Scratches (Part 2)

So I tried to fix our copy of "The Wonderful Wizard Of Ha's" because it was scratched really, really badly. I tried bananas and toothpaste, at it didn't work. So I just a few minutes ago, I tried another method that involved diet coke, paper towels, peanut butter, and baking soda. It did not work. I don't really know why. I think it's time to head to eBay.
