It does seem to be a problem on the IDE channel. I think that if you get many of these, XP will cut the DMA down to DMA mode 2 or PIO. That's not usually a cure though. Especially PIO mode is a bad thing because you will get high CPU usage and show burning.
I'm not sure what the problem is. If you search for that error message, you will get many hits. In at least one case, the problem was the 40 conductor cable, but not in all cases apparently. It could also be a damaged cable or one of the connectors could be loose.
Just in case, you should try different media to see what happens. As has been said, multiple burns can degrade the burn quality quickly. How quickly depends on the quality of the media and the ability of a particular burner to handle DVD+RW. Most burners do a lousy job. My best DVD+RW burner is my old Lite-On 1693.
I think Verbatim DVD+RW discs are the best and Ridata and Memorex are the worst.
P.S. I've never heard of a fixed cable. Are you sure it isn't plugged in to a connector on the motherboard? These darned cables are a hassle. If you unplug or re-plug the cable on the motherboard, try to not put too much stress on the mobo. Mine are near the edge and I try to support the board when I yank or push.
It will be good when everything is converted to SATA.
