How do you get scratches off of disc

See if you can purchase a kit for removing scratches on discs.

But what do you do when the disc came from the manufacturer with BAD DISC or scratches on certain parts, and every disc that you've seen of the same dvd, cd, computer disc, or game disc happen to have the same exact scratch marks.

There has got to be a better and cheaper solution then having all of the following when I want to watch discs:

A DVD

a DVD RECORDER

A PLAYSTATION 2

A COMPUTER, with disc drive, which was a recent present.

in case Most or all of them will not play a disc or act up, which has happened in just bought discs from stores or on the net.
