I had one to, that I love. The key gen didn't work on demo version for vista (you enter a key, and the demo turns into a permanent version of that), So I'm stuck with essentials... for now.
At any rate, I have never had problems with Nero. It has done any thing I wanted a burning program to do.
Nero 7 Ultra Edition ENHANCED v7.8.5.0 Full Multilanguage - NOTE: Vista ships with DirectX 10. Will not install if you choose not to install the directX component. The software is compatible in all use. (32-bit) - NOTE: Version 7.7.5.1 is the minimum for Vista Compatibility (Installs as 32-bit under Vista x64)
I have Sonic Digital Media Plus 7 that works fine. I also have Nero 7 Essentials that came with my DVD burner, also works fine. Only problem I ever had was that I had a bad batch of DVDs once, all 5 in the pack didn't work (8x DVD+R Memorex). I bought myself some new DVDs (16x DVD+R Memorex) and it worked fine burning the same exact image that I had attempted 5 times before.
THat sucks. I use Memorex also, but I've had very good success with them. I use the 8x DVDs, mainly the DVD+R. For my car, I always use the CD+RW so I can always change songs when I need to. Same brand and Ultra Speed for that part.
To prove that my PC is that old, I don't think my DVD burner can support 16x DVDs, lol.
