Re: Copy protected CD's
Find detailed information about copy protected CDs (if you can read German):
http://www.heise.de/ct/03/09/112/default.shtml
http://www.heise.de/ct/cd-register/.
Some facts I remember from reading the article:
These CDs are not 100% compatible with audio CD specification (the author calls
them unCDs).
They can be played on some drives, it seems to depend more on the hard- and
firmware (though I found cdparanoia is better than windows).
Sometimes tracks in wma format (with drm) are added to these CDs to be played on
(windows) computers.
