Re: This article on CNet.
How does this copy protection work?
It would be interesting to see what the technology is exactly. I do not understand how an audio distortion will prevent correct CD --> .wav copies, assuming the drive doing it does good quality rips. On the other hand I can see how certain types of sound distortion could wreak havoc with certain .wav --> .mp3 encoding algorithms, resulting in unwanted weird sounds. Of course, if the watermark is attacking this particular part of the process, then I'm sure that one can revise the encoding algorithms to compensate.
Interestingly, this sounds a lot like when a crappy drive doesn't rip properly --> clicks and pops. However, I would be surprised if they were messing with the integrity of the disc storage method, because that would likely make the disc unreadable on some machines (like mentioned in the article).
Which CDs have been copy protected?
