How to Redirect Wordpress Podcast Feed to a Feedburner feed in iTunes

Hi all -

I've recently added a wordpress podcast feed to iTunes: http://www.thestdproject.com/podcasts/feed however, I'd like to redirect iTunes to my podcast feed on Feedburner instead: http://feeds.feedburner.com/TheStdProjectPodcasts.

I know I need to add the iTunes redirect after the channel tags and before any items: <itunes:new-feed-url>http://feeds.feedburner.com/TheStdProjectPodcasts</itunes:new-feed-url> but I'm not sure HOW to go in and edit just the wordpress podcasts feed.

Today, I accessed my cpanel and added the redirect to both the feed-rss2 file and the feed-rss file. Is that all I need to do and it will carry through to the individual category feeds as well? (The wordpress podcast feed is a separate category on my wordpress site.) Maybe I just need to wait for iTunes to recognize the update? Just curious if I've done the right things here.

Thanks in advance!
