Hello everybody,
Some more of those potentially insulting questions (about things that happen a lot):
Did you burn the ISO image to the disk and not the ISO file itself? Examine the DVD with a file manager like Windows Explorer. If you see the ISO file that you downloaded, then you did the latter. If you see files (fedora.css, RPM keys, etc) and folders (images, isolinux, Packages), then never mind about this.
Did you use a brand/type of media known to work in your drive? Sometimes rewritable disks don't work as well. And not all brands of disks always work well in my drives. Sometimes burning at less than the disk's maximum rated speed helps.
Did you verify that the downloaded ISO file was good? You can generate a SHA-1 hash with various utililtes in Windows (
sha1sum.exe,
HashCalc) and compare the result to the hash in the file SHA1SUM on the server where you got your ISO file.
My apologies if nothing I said was relevant. I had no way to know, and this stuff happens all the time.
