Welcome to the forums BlueBulldog.
I don't really have any help for you with Nero. I quit using it back at Nero 6 or so, and have used ImgBurn ever since with no issues. But I didn't want you to think you were being ignored. Most of the regulars here simply don't use Nero anymore.
It looks like your laptop doesn't come with an internal drive, and can use optical drives through USB only. Since Nero is asking for a disc, it can obviously find the drive, but cannot confirm the disc is present. And since other software is not having issues, this sounds like a problem within Nero entirely, and cannot be solved by adjusting settings in the operating system, or by hardware changes.
You've tried other discs, but do you know for certain that they use different mid codes? I would advise using Taiyo Yuden or Verbatim AZO DVD's. Have you tried burning a CD?
If the other software works correctly, is there any overwhelming reason to use Nero? Most of us have answered that question with a resounding no for many years now.
