couple questions... please don't take these the wrong way

1) Are you sure you have a CD/DVD burner? What is the model #?
2) Are you sure the CD's are indeed blank?
3) Are you sure you are putting them into the drive the right way (label up)?
4) Are you using NERO express or the Full Nero..? Does NERO present any errors during the burn and/or show a progress bar?
5) What happens if you put the disc in the drive and then use explorer to look at the contents?
6) Have you tried other brands of discs and/or taken the "blank" ones to a different CD/DVD drive to try reading them there?
7) Are you using the multi-session setting? What if you set multi-session to No?

Thx!
