Thanks for the quick reply.
I just went and checked that the DMA is enabled. I have IDE channels and two of them have the option to "Enable DMA" Channel 0 and Channel 4 were already enabled and were the only two that showed the box to check to enable it.
Channel 0 read ATA Disk under Device Type and Ultra DMA Mode 5 under Current Mode.
Channel 4 read ATAPI Cdrom under Device Type and Ultra DMA Mode 5 under Current Mode.
The other channels had no options in the Advanced Settings, but all say that the device is working properly in the generel tab.
I'm using Fuji Film DVD-R with up to 8X write speed made in Taiwan
