Disc burner in use by another application
When attempting to burn a CD through iTunes, my blank CD is ejected and an error message pops up reading "The disc burner is in use by an application other than itunes." I've shut down every program related to reading/burning discs, but I'm guessing there's an app. running that doesn't show up on the tray on the bottom right of my screen. I've got a Dell XPS Gen. 3 desktop which uses windows XP. Please, any help would be greatly appreciated.
