DVD arrived, still not satisfied

After the company ordering system said that it would be several days before I got my DVD burner, my boss sent his secretary out across the street to Staples, who have one on sale for $50. I got it and installed it, but unfortunately I can’t burn to it. I get the following error:

I think I’m going to have to shut down again and check that I’ve got the devices jumpered correctly.
