It works in a way no standard CD burner can work, IIR. It does create
non-standards-compliant CDs with "errors" that *should* only affect CD
drives in computers.  See for example this in-depth doc: 
http://www.cs.princeton.edu/~jhalderm/papers/drm2002.pdf

It does affect several hifi-CD-players as well though, for example
mine. That's one practical reason why I don't buy copy-protected CDs.
Funnily I once *had* to buy a DRM-CD (Paddy McAloon) because there was
no vinly version. It didn't run in my hifi-player, but could be
grabbed with cdparanoia withouth problems and be reburned to audio-CD.
Thank god they didn't do it right.

The major music industry has lost me as a buyer, and I was a decent to
good customer. May they rot...

ciao
