How do I use NeroSpeed to scan burned DVDRs for Quality



How can I scan burned dvdrs for errors
I go to Extras>Disc Quality Test
but the start option is grey out.

I can only use DQ Test to scan unburned media.

Can someone tell me what to do?

Using NEC 3540A
want to test some burned TY02s and some Sonys


I am not sure if CD-DVD Speed supports NEC 3540A. Try looking in NEC forum see if people post any scans by that drive. Or check the sticky thread
