Thanks Liam,
I have never had any version of DirectCD installed on my computer let alone versions 4 or 5 so I'm at a loss to know why it's coming up.
I presume that a driver linked to it has been installed via Windows media player or some other program so have inherited it by default.
I use Nero for CD/DVD burning as it came as an OEM addon so I doubt that I've got this bug through them.
