tekochip: I mentioned in a previous comment that I have a tin ear that can't tell the difference between the sound quality of vinyl versus digital. I've been told for years that digital can't measure up to vinyl and I wondered why vinyl didn't sound better to me. Your comment is heartening -- maybe my assessment of sound quality isn't as bad as I was led to believe. Thanks.

:-) while I agree you should treat your CD's/DVD's that way, they are incredably tolerant of scratches etc. because of a combination of good error correction algorithms and some cleaver schemes to deal with complete loss of signal. Where as a scratch on vinyl produces a click which is spectrally different from the content, a CD player extends the last detected audio level which barely changes the spectral content and so goes largely unnoticed. One thing CD's don't like is exposure to sulphur. High sulphur paper can blacken the silver reflective layer causing much more significant effects than a few scratches might.
