This is my first post here - in fact I just joined after landing here off a Google search for the 'dark spots' problem. I have it too and it's rather annoying. Has anyone determined if it's a problem with the burner, media, software, etc or just what is causing this? I'm making a set of 10 DVDs. Of those, 2 work in home DVD players. That's an 80% failure rate. I, too, notice when shining a flashlight on the burn surface, you can see small dark spots in various places and also dark streaks. I've learned now to look at each burn surface when done burning and if either of the above is seen, chuck it in the trash, cuz it's a coaster. Does anyone know what the cause is?
Thanks for any help,
