When you don't know what you're talking about, please save the network bandwidth by refraining from posting. You clearly haven't a clue about the way error correction is done on CDs (it's done by error correcting codes) and your phrasing ("I think", "I assume") indicates that you're making it up. -- Joe Buck jbuck@galileo.berkeley.edu {uunet,ucbvax}!galileo.berkeley.edu!jbuck
