Ok, here's the simplest way I can think of. Start here: http://www.foxnews.com/rss/index.html

Click on one of the links you want and it'll take you over to the RSS feed. (this doesn't work by going there directly for some reason as it determines what it gives you by your cookies, and if you click through it'll give you the choice of changing RSS types). Now, in the upper right hand corner is a link that says "Show all subscription options." If you click that, it'll give you a list of seven different formats you can use. Play with them until you find one that works. I just use the outlook version and then use a parser in turn to rip the latest stream links.
