The toothpaste trick had me skeptical at first as well, but HSU is on the money (as usual). It works damn good on even the most finickey surface scratches. rawr.

I usually use a gell toothpaste on my teeth, so I keep a tube of the solid white on hand for such ocasions. If the scratch is pretty deep, or I am just lazy, I found that most music stores, or video rental places will gladly clean discs for you for a small 2 - 3 dollar fee. Definatley rendering the disk doctor a worthless buy.
