You're trying to burn on the fly, and in spite of having burnproof your dvd drive is fluctuating and playing outside the rate that the cdrw can copy at.
the solution is to untick copy on the fly and let nero make an image that will then be copied to the cdrw when it has been copied in it's entirety.
It's a bit slower but almost guaranteed not to have any errors.
I get the same problem on most audio cds but almost never on data cds
so on the fly copying is out.
It can also be caused by using cheap 8/10/20 speed whatever blank cdrs and trying to burn at 40/48 speed
