Have used nero since nero 4. When i purchased nero 8, i found my whizz of a machine sluggish and when processing crashed other programs used in the background. Reverted to nero 7, when this version came out purchased it and found the same thing but with shiny corners. The only advantage to nero 9 is the program is i can assign 1 part of my multi core processor to work on only this. Program dedicating 1 ghz of power to it. Reverted back to nero 7. My advice is if you can get nero 7 still, do!! Don't think i will be buying nero 10 unless major improvments are made.
