How do I finalize discs from a standalone recorder in a burner? I only have what came with the burner, Nero Express, In CD, Power Producer Gold. I've been all through them and haven't seen anything about finalizing. Do I need something else? If so what do I need? Also when burning with Nero there is an ultrabuffer that says not to set over 40% of the computers memory. Do I want to set it as close to 40% as possible? Is higher better? One more thing, when copying a DVD-R from a standalone to a DVD-R with Nero, I've noticed it uses a little less disc space on the copy than the original did. They say it's an exact copy, so why does it use less disc space?
