Thanks for your response! I have had some mechanical problems with my BenQ drive and I bought a new one from LG (GSA-H42N) because of its accurate results. But 'til now I am to lazy to build the thing in my PC. Maybe now's the moment...
With this LG drive I got a new Nero 7 package, but it seemed to me that some important video options are missing in this package. That is why I have installed Nero 6 again.
Another question to you, if I may be so free... When I make a data DVD compilation, I save a Nero .nri file on my desk top. That's handy when the DVD fails; a new one is burnt easily. But most of the cases when I double click the .nri icon i get a Windows message that the nero exe file is changed because of a virus (I don't have any) and that I have to install Nero again.
I tried this of course, but it only helped once. The next time I had the same message and burning wouldn't succeed... Is this a known issue?
