Since this system was not cabled like the system here that has a Sony drive that works I decided to re-cable it. This is what I wound up with:
1. The C: drive and the Sony burner are on the primary IDE bus.
2. The Pioneer reader and a pluggable drive are on the secondary bus.
3. The D: drive is on a added Maxtor bus.
Now it readily burns at 4X! Not only that but the CPU utilization now varies between 4 and 7 %. What an improvement.

Thanks to all of you who have given me information and encouragement for the last couple of months. I never would have believed the placement of a drive on a bus would make a difference in how fast it burned.
Thought some of you might like to know.........
