This raises some questions: 1) Presumably the DAT recorder will keep an internal table of (CD-ID, copy-count) pairs. (Just marking copies won't work: a copy of a copy could be stopped, but you could still make unlimited copies of the original CD.) How much memory in the DAT recorder will be devoted to this table? 2) How much will this affect the price of a DAT recorder? 3) What do you do when there's no more room in the table for new (CD-ID, copy-count) pairs? (Buy more memory for your DAT recorder? :-| ) Also, flagging A/D copies as copyrighted DAT prevents me from making unlimited digital copies of my own digital masters, just because my mixer has analog outputs. I have to buy a mixer with digital outputs, or put an A/D converter between the mixer and the DAT recorder so my master will be flagged as non-copyrighted DAT. Pardon me while I throw back my head and scream. kyle jones ...!uunet!talos!kjones Up ahead someone uttered a gobbling scream, and then the rifles crashed in unison.
