I have a NEC 3500AG with the latest firmware 2.18. Every time I try to burn with the multisession off (so it's a final disk in other words), the buffer stays at zero and the progress meter stays at 0. I am running: P4 2.4 512 DDR 40 GB 7200 HD Win XP Pro. My media is Ridata - R05 DVD-R 8X. Any help would be much appreciated.
