I really need to see why the command is failing.
To do that I need you to enabled 'I/O Debug Mode' just before you burn.
Simply press the F8 button before you click the 'Write' button.
Then once it's has errored out, press F8 again to disable 'I/O Debug Mode', save the log and attach it in your next post.
btw, can I assume you've at least tried cycling the power on the PC?!
