I purchased Nero 10 HD platinum, or whatever silly name they have for the full package, when it came out. So far my only complaint is with the automatic update feature. I am running Windowd 7 professional, although I don't know if that makes a difference.
Nero has made an improvement, from what I can see, in the automatic update, via control center, although it has a really annoying flaw.
After you click update, the files download and install, control center returns and informs you there is a new update. Unfortunately it is the same update it just installed. In order for the update to be completed, your computer will need to be restarted, although there is no notification of this. If you let it, control will keep downloading and installing the same update until you disable it or restart your computer.
I have asked Nero to please include a little bit of code to not look for updates until the reboot has been completed. Hopefully they will fix this problem soon, but other than that I have not found any problems, although I have not had a chance to fully explore the software. I have encoded and burned a few DVDs and everything worked fine.
