Sounds like you are erroring out before you get to the media check them. Try checking the md5 sum of the ISO you downloaded against the MD5s on the Fedora Web site. You can find a Windows MD5 checker here
(note I don't generally use Windows, so I haven't tried this. It's the first thing that popped out of Google.).
If the MD5 sum is correct, try burning the DVD at a slower speed. That has helped me in the past.
