Well it installs OK under Vista; but it doesn't seem to have been very well tested (oh I forgot, we are all Nero's unpaid beta-testers)
Specifically, lots of RunDLL32 crashes & COM surrogate error boxes when I open an explorer windows full of AVI / MPEG / MP4 files (what are you betting Nero Scout is at the root of that one). Installation also seems to critically damage the running of Windows Media Player 11. MPeg files playback all purple & green and WMP11 hangs and needs to be kicked out. Vista is then totally unstable until Windows is rebooted.
(Advance Warning to Nero: I do not intend to PAY for any more upgrades of this unstable bloatware. I still wait & hope that Nero 7 becomes stable and bug-free; however, Nero is NOT coming with me to Vista and I will cease to be a Nero customer when I move on from WinXP).
