Yumdownloader Problem

[Robert L Cochran]

I want to download the current kernel-source package using 
yumdownloader. Here are my results. Can anyone tell me what I'm doing 
wrong? Please note that I am really unclear on how to specify a "repo", 
or where to find a list of current repositories valid for Fedora 7 
source code.

Help is gratefully appreciated.
