Ray:

Thanks for the detailed reply. I  have found a reference to DMA support in 
RH 8.0 that you mentioned (ain't google wonderful!):

                         http://linuxline.epfl.ch/Doc/rh-8.0/RELEASE-NOTES.html

which includes this:
DMA is disabled on CD-ROM drives in this release in a different but more 
reliable way than previously. If you are sure that your CD-ROM drive is 
capable of IDE DMA, place the following line in the /etc/modules.conf file:

options ide-cd dma=1

I will try this later and see if I can then enable DMA for my DVD drive 
(/dev/hdc)
