Nero cannot read a SafeDisc v-2 protected CD, nor StarForce nor Tages nor Ring PROTECH nor ProtectCD nor LaserLock 1 & 2 nor SecuROM v-4.8x, hehe.
From an image, it can write old versions of SecuROM, all versions of SafeDisc, early versions of ProtectCD and LaserLock 1 & 2 using dao96 but certainly not the others
Keep Nero for premastering and duping non-protected CDs and DVDs, MP3s etc.
What you use for copy protected CDs is now a matter of choice (and some research!) but Alcohol 120% is probably the pick at the moment.
