I'm having serious problem regarding ISO burning with Nero.
Nero version is 18.104.22.168, and everything burns fine except ISO. So burner nor Nero is not the issue, and I hope it is not.
So when I put ISO, not as putting actual ISO in Nero, but double-click ISO, and Nero opens, and I burn DVD, when testing it with CD/DVD speed, it passes without errors. But actual files within, when I start to copy them onto HDD, because I always test it that way, doesn't want to copy.
Remember, this only is a problem with ISO, other burning is fine.
