Multi-Word DMA 2 indicates that Windows is trying to turn DMA on.
Your computer has U-DMA shut off.
This could be an installation issue, a bios setting or a driver issue.
A high quality 80 wire cable in use, connected to the motherboard's secondary IDE outlet, and nothing else but the BenQ, would be an optimal installation.
In the BIOS, standard screen, the channel in use (recommended Master of Secondary IDE) should be set to Auto Detect with Auto Type. Also in BIOS, check around to see that UDMA is not set to disabled.
If a previous optical drive was connected to exactly the same IDE port AND that previous optical drive did not use UDMA, then you may need to clear the CMOS to get it "unstuck" from the protocol used by any previous drive.
If these steps do not clear up this issue, consider a visit to the motherboard manufacturer's web site to get a BIOS update.
If you are not using Windows XP, then you may need to visit the motherboard chipset manufacturer's website for updated chipset support drivers. These are not usually necessary for Windows XP.
P.S. That IS a decent Daxon AZ2 burn. Check playback in your set-top player to determine appropriate write speeds for this media. If choppy, then slow down.
P.P.S. The expanse of yellow PI failures completely across the graph at the very low "1" level on the Optodisc scan is caused by "UDMA disabled at motherboard" issue. Those errors will be much "thinner" once UDMA is switched on.
