Painful

I already host my own rss feed and podcast files. I just want to point to my feed so I can use the player, subscribe links, etc. But Blubrry insists that my feed is http://mysite.com/feed/podcast/. When I go to the destination tab and type in my real feed it just gets reset to that link.
