Newbie Question: I have purchased a NEC-2500A and I've burnt 13 coasters (also 12 good burns, that work fine on my DVD player) using DVD-Rs. When these burns fail, it is following/during the lead-in section of the burn within Nero. All coasters are left with a burnt ring approx 1 inch from the centre, and are complety useless. When a coaster occurs Nero and the PC hang and the PC needs re-booting/powering off.
I have tried 4 media types (Ritek, Databank, Princo and UL-Tran), Ritek and UL-Tran produced some that worked and others that did not. Problem has gotten worst, to the stage were I can not burn any DVD-Rs now. The funny thing is that I have two DVD+RW disks (Digi Media), and these work fine every time (I can erase and copy multiple times without any errors).
The NEC drive came with Nero 6 OEM and I have upgrade the latest version from the Nero site. I have DMA enabled. PC specs 512 RAM, 1.1 Athlon CPU, ASUS A7V133 Motherboard. I'm using DVDShrink to rip the DVDs.
