Scary stuff - makes you wonder how everyday users are supposed to protect against this ...
Personally I use software which automatically hides copy protection on CDs and DVDs from my system altogether. That way any CD can be used with any player, and any DVD can be used without 'infecting' my system.
Whilst this may be seen by some as potentially illegal, I would defend my right to do that in a court and counter it with a lawsuit of propogating viruses illegally.
