Finally decided to try burning a dual layer DVD but I keep getting a disc at once error. DVD burner NEC ND-3500AG DVD software Nero 8.2.8 Blank DVD Fujifilm DVD+R DL The burner burn's any regular DVD I throw at it no problems. I first checked the DMA and downloaded the latest driver. Hard drive is running at Ultra DMA 5 Ultra 100 and DVD burner is Ultra DMA 2 Ultra 33. It runs on a 80 wire 40 pin ribbon. I also defragmented the hard drive, Tried to burn at 2.4x speed, whatever else I could think of??? Starts to burn and immediately throws up a disc at once error. Anyone have any ideas?

Have you tried NEC's web site?

Can't find anything there about it and support is down. All I found is firmware which I have 2.16 and the update they have is 2.1A. I don't know if it's worth the risk trying to update the firmware for a disc at once error. I would assume fugifilm is a good quality dvd +R DL.

Below is a link on the NEC site, which is now working. The link is for compatible media. http://support.necam.com/Optical/nd...
