what problem are you having?
open nero (classic view)
in the window - new compilation
top left - select either Cd os DVD
underneath
select dvd to dvd (or cd to cd)
press copy
drawer opens ... insert DVD to be copied
whizz whizz
drawer opens - insert dvd to copy to ...
whizz whizz
drawer opens .... done
of course you do need a dvd burner .... and some empty disks which are the same size as the one you are trying to copy (single/dual layer)
- can't remember if nero limits the size of copy until it's registered - these are free
