Who said anything about "a complex program"? All this discussion refers to audio (CD-DA) exclusively. And who said "windows will make a more exact copy"? I said Exact Audio Copy <http://www.exactaudiocopy.de/>, which runs only on Windows, will -- which is not the same thing, and which referred _exclusively_ to CD-DA. > HooRaw is what that is. 1's and 0's .

With all due respect (which I'm not sure the "HooRaw" deserves), I'm afraid your understanding of CD technology is somewhat incomplete. I suggest consulting a book on the subject, such as Boden, L. (1995) "Mastering CD-ROM Technology" Wiley & Sons, New York: 384. ISBN 0471121745, or, better, Watkinson, J. (2001) "The Art of Digital Audio" Focal Press, Oxford: 736. ISBN 0240515870. You're looking for "error correction". <0x0192>
