I am using Dvd encrypter,Dvd2one and copytodvd. I have back-up several dvds with perfect picture quality. Some of them new and some old. I have cleaned the dvds with just a lintless cloth only.

My question is would getting one of those cleaners for dvd/cds help in removing some of those old scratches in a dvd. Some of the dvds that have minor scratches seem to effect my picture quality. I have heard that dvd2one doesn't always produce good picture quality. The picture is alittle grainy but when I put in the original dvd it is the same picture quality as well.
