Just wanted to say thanks to all.
I finally found a place with real info.
After burning about 12 copies of AOM I found out the problem was not the images, but my writer (40X but no sheep).
Went out and got a LTR-48246S and it worked perfectly with Alcohol 120%.
Just in time, since my original Disk 1 of Emperor Battle for Dune gave up yesterday. Fortunately I made an image of it about two weeks ago.
Thanks for such a great forum to all mods.
