Most likely all of your CDs are fine. Try booting using "linux ide=nodma".

You can check that your ISO downloads are OK by comparing the md5sums with 
those published on the download site:

md5sum -c MD5SUM

where MD5SUM is the file of that name in the iso directory that you downloaded 
the ISO images from

You can check that your burned CDs are OK by getting the data back off the CD 
and either comparing the file with the original ISO or checking its md5sum.

dd if=/dev/cdrom of=burned-iso-1.iso bs=16384
cmp burned-iso-1.iso FC3-i386-disc1.iso
md5sum burned-iso-1.iso  (then compare the result with that in the MD5SUM file)
