Thanks for the warning. By the way, this is not the first time that Sony is up to no good. Back in 2002, their attempt at copy protection could crash your PC, and do worse damage to your Mac. For some historical perspective, here are some links to reports from back then:

* Celine Dion disc could crash European PCs
* Marker pens, sticky tape crack music CD protection
* Dion's CD can crash PCs
