Ok, problem has been fixed. Search of forums solved the problem.
SP3 and Office 2007 were not the problem.
I had a bad disk a week ago. Apparently, Windows will change the setting of the drive from DMA to PIO. This slows the data transfer rate significantly.
I uninstalled both the secondary IDE controller and the dvd burner. After starting up the computer, DMA was enabled. Nero and my burner were back to normal. Disks burned in 6 minutes vs 40 minutes.
See http://forum.videohelp.com/topic187112.html for details on what to do.
There was some advice on how to change the setting from PIO back to DMA by going into the registry, but there is some risk in doing so. I found that uninstalling the IDE controller and burner worked without having to fool around with the registry.
