I have the same problem with Nero, but it is intermitant. So I just stopped using Nero and switched to Alcohol 120%. I didn't do it immediatly though, I sent a couple of messages to Nero tech support, and when they ignored me, I figured it was time to switch.
I also have an ATA133 HDD, DMA enabled, and my HDD is capable of transferring data much faster then the burner needs, according to Fix-It-Utilities.
I tried again with the latest version of Nero, but the speed test always sets the burning speed to 20x. Sometime's I can burn at 40x/48x if I don't do the speed test first...but I don't want to do that because I don't know the speed it will write at, and I've had buffer underrun errors caused by it before (thank goodness for burn proof!)
