It's fairly simple. Such menus pop up if you put in dual layer DVD media. You get 9+GB reported as the disk size.

I have an NEC ND-2510A Dual layer burner with a bundled OEM copy of NERO 6.3.0.5. I have used both to burn mp3 music discs but I can't find any reference to burning dual layer discs. Can anyoen help?
