You do not need to format a regular cdr you just have to have burning software installed and usually you will need to burn using the software not Jukebox. There may be a utility in Jukebox but I would trust a program designed to do the burning as its main function.
If you are trying to burn to a cdrw you may need to "clean" the disk before you can save anything else to it.
I hope that helped if not let us know
