Pretty sure this problem is new for me, but I have not tried these discs in a while now. Says incorrect disc type, and won't begin burn for any type of compilation, be it ISO, DVD video, Data, nothing. Is this new, or am I being a newb? Tried on Nero 7 & 8.
Thank you, Cyprusrom, for pointing me in the right direction! Updated firmware and am burning like George Micheals libido in a men's restroom! (yes, gross.)
If your Nero misbehaves on those DL burns, free ImgBurn will do them flawlessly and probably better. Always use Verbatim DL discs Made In Singapore if you can find them.
