Alright, I got a NEC 3520AW burner about a month ago. Lastest firmware [3.05] I've been burning fine, then recently it started screwing up all the burns and I have about 50 coasters after many attempts at burning with different configurations. Someone told me it was bad media, so I purchased Maxell DVD-R, same thing and two extra coasters. Here's my Nero InfoTool file if anyone wants to know the spec's. Any help would be greatly appreciated.
