I'm still using Nero 7 but only for creating (Viurtual) Audio CD's which I then can burn to Minidiscs (yes I'm still using those).
I mount the Virtual CD with Alcohol 52% Free edition -- it can handle the .NRG nero format. The MD transfer software then burns to MD. Ultra ISO doesn't like mounted Audio .NRG files.
I only use Nero as it can create Audio CD's directly from my FLAC files and write to a "Virtual Audio image file" -- that's ALL I use it for --everything else is just bloat I'm afraid.
If you just want burning / ripping DVD software there's a lot of better options out there -- if I could find a decent "Create Virtual Audio CD images" from FLAC files I'd dump Nero in an instant.
For "Cloning" DVD's (even Blu Ray) Img Burn works fine on Windows 7 even X-64.
