I'm using Nero 7, so it does not apply.
It happens in all programs, CloneCD, CloneDVD, etc. Also why would a whole bunch of unreleated peoples' drives across the world all of a sudden start dying at once? I'm sorry but posts like this really bother me... it's harmful to the program's development, not helpful, as it possibly delays the time it takes for the developers to realize there is a problem and fix it.
It's almost like you take it personally as an attack on AnyDVD or something, when I'm just trying to help bring a problem to light so that it gets solved. And by ignoring the problem or attempting to pass it off onto other programs, you make it worse by delaying a fix.
I believe it's only happening with certain DVD writers and firmware. So if you have a drive or drives that don't have the issue, then of course it won't appear to you as if there is a problem.
