How can a CD-RW drive determine a CD-R from a CD-RW? It's the disc substrate material. It refelects different light fequencies, which makes all the difference. You may want to try the original type of DVD-R from the late 90's.
On the first xbox, GD had an extra TOC (table of Content) located beyond the standard DVD TOC, wich in this case refered to a Video DVD. The GD were usable on a xbox original drive because it's firmware made it looks for the non standard TOC before the standard one.
About writable medias, i thought they also had a special track containing their physical characteristics, thus letting the burner sets an appropriate laser power and writing speed... But I may be wrong
