The Nero software has been good until the version 7 release. I read people where having a lot of trouble with it so I stayed with the last version, 6. I did try their NeroVision Express 4 but it was too troublesome for me, so I reinstalled the 3.0.16 version and all is well.
Maybe by now they've patched the problems, but I'd recommend checking out the Nero oriented forums. I think there's some pertinent comments on here -
