Answer 2

I think you mean is when you insert a CD/DVD in the drive, some just open (like an autorun) while others need Nero to open, is that correct?? it could be because if you have a CD/DVD which already has some data on it, will open automatically, and if you insert a blank CD/DVD in the drive, the writer detects it as a blank and hence Nero opens asking if you want to write on it..
