7-16x CAV Transfer test on a Blank DVD? 
My Nero 3.55 can’t do that.
We usualy do Create Data Disk (F9) and Nero will fill the disk with data, then Disk Quality Test (Extra menu) and transfer test.
Yes it can - if you use DVD-R discs 
DVD+R format do not support simulation while DVD-R supports it.
As you can tell im new to this forum and just getting started with this kind of testing. I have been trying to figure out all this. So I’ll what you said above and see how it goes got my fingers crossed.

PX-716A/SA/UF V1.03
