I've been warned against the upgrade to Nero 8. It is not DVD Shrink compliant and many DVD's that are burned with it are not playing on stand alone players. Nero 7 was a good version of Nero, but I think I'll wait until the updates are in place before purchasing the latest version of Nero.
At this stage I cannot see any reason to change from 7 to 8....me, I'm still using 7.5.9.0 and content in the fact that it does what I want it to do.
I bought Nero 7 when it first came out and it took them a year to work out the bugs. I don't plan on repeating the mistake I can wait to buy 8. I am using Nero 7 ver 7.8.5.0 and having no problems.
