you can't set booktype Rom on a DVD-R.
You can only do the bitsetting on a dvd burner that supports setting bitsetting to dvd-rom. Not all DVD+R burners allow that and you may have to reflash the firmware to do that and invalidate your warranty.
shows how much you don't know.
as for media maxell and TDk are not the greatest, Taiyo Yuden are the best.
