I agree with Steve. Nero is an intrusive piece of software that takes over your PC and should NEVER be installed on a video editing workstation.
I had problems with Nero back around version 7 or 8. It took over my DV filters and caused Boris RED not to be able to load any DV footage. I uninstalled Nero and RED works, I re-installed Nero and RED stopped working. I tested this on both my desktop and laptop and it was definitely Nero that was causing this. Using GSPOT I could see that Nero had inserted a DirectX Filter into my PC's chain of processors for DV footage. I even tried installing JUST the Burning ROM and no other utility and it still did this (and it had no business messing with my video filters just to install a CD burner program).
Nero 6 was the last time I recommended Nero to anyone and now I recommend that you AVOID IT LIKE A VIRUS!!! I use ImgBurn and BurnAware Free for all of my disc burning needs and they work like Nero used to.
