The Nero 18.104.22.168 update added Nero_LS_ENG.CHM, a help file for the new LightScribe direct disc labeling capability.
Under Requirements, this file says LightScribe needs a 500 MHz or better Intel CPU (in addition to the proper CD burner and Windows 2000 or Windows XP).
One of my computers is based on an AMD Sempron and the other (an ancient Pentium) runs Win98SE. Thus it seems pointless for me to buy a LightScribe-enabled CD burner. What's up with that?
