To burn multiple copies at the same time, click the multiple check box as you have & then when you get the choose recorder window left click & drag the cursor over the recorders you want to use. When they are highlighted blue click ok & off you go.
You may have already sorted it out by now :)[/QUOTE]
I just used Nero 9 to burn 4 DVD’s at the same time to different DVD burner types and interfaces:
D: = EIDE Internal DVD Burner (also acted as source)
E: = SATA Internal DVD Burner
F: = SATA Internal DVD Burner
G: = USB 2.0 External DVD Burner
It took exactly 10 minutes from start to finish to burn 4 copies of a DVD. This works just as good as the DVD duplicators I’ve used. It’s not one touch like they are but will suffice for my needs and didn’t cost me $1,100.
