With such a drive wodim should _not_ answer:

Profile: 0x002B (DVD+R/DL) 

when inquired by:

  wodim -v dev=/dev/sr0 -atip 2>/dev/null | grep '^Profile:.*0x002B'

If a DVD+R/DL disc is inserted, then the
answer with a DL capable drive should be:

Profile: 0x002B (DVD+R/DL) (current)


Regrettably i got no non dual layer DVD burner
any more for testing the lack of profile 2B.
My DVD-ROM and my CD burner do not report it.


Have a nice day :)
