I can now download and burn ISO files into Linux disks. I found out what was wrong with all my previous attempts. It was a combination of 2 things.
1, I set the burn ratio to fast. ISO files are compressed, but while burning they need to decompress. If they are set to fast, they will burn compressed and curupt.
2, My mother board and/or my CPU was causing many of the problems. I often got this last message when the CD would boot up, Starting vectoer 00000002, blah blah.
Something was not processing correctly with that mother board.
I know this because I got tihs error with a few cd's that I burned, asuming they were curupt. When I setup my server with an Intel CPU on a ASUS motherboard, they worked, "PERFECTLY".
If you get a Starting VECTOR 000002 as your last line on a boot up and your computer freezes, it may be due to a compatiablity issue.
