With the sophistication of this "anti piracy" software and other devices which CD publishers are using to prevent illegal copying, I wonder what is to stop anyone putting the "protected" CD's into an ordinary CD player and digitising the analogue output. There would be little loss in quality and all the tracks would then be totally unprotected. A (say) 15kHz low pass filter would remove any ultrasonic nasties which had been applied as well, so isn't this protection a bit OTT?
P.P.
