My podcast is registered for use with iTunes as http://marspodcast.com/feed/. I would like to change the feed to Feedburner, but can not find anything in my dashboard that will allow me to insert the code iTunes requires to change my feed. Their document states that they require the addtion of <itunes:new-feed-url> in order to change the feed. In my case I believe it would be <itunes:new-feed-http://feeds.feedburner.com/MarsAttacksPodcast>. I can’t find anything on the support forum regarding this topic. Does anyone know how I can change the feed?
