Do you have any other CD burning software on board like Nero?
EDIT: Don't answer that. I've just looked at your HJT log and you seem to have at least three things running at startup that could be conflicting with Windows MP trying to burn a CD - Clone CD Tray, AnyDVD and Ulead. What are they all for?

Do you know that we're all in line for succession to the throne? Really?
Well, if forty-eight million, two hundred thousand, seven hundred and one people died I'd be Queen.
