Info - CD copy protection

Folks, have a look at this link :

I tought I heard some clicks on a CD I bought yesterday. I'll listen to it again tonight and let you know.
OK, so this prevents us from recording back-up copies or mixes. The big pirate companies will, I suspect, easily find a way around this. But Macrovision will make lots of money as will the companies who will spring up with their black boxes. Thanks for the info.
Clicks and pops on CDs? What'll they think of next. One step closer to vinyl...
Ok, so what cd is it?
Anything like that added to the signal or digital information will probably degrade the sound quality.
Sorry. It was false alarm. I listened that cd again - no clicks.
