Archaic Christianity

So now feedburner is irking me. I try to view my feed and it says I have three question marks appended to the beginning before the xml declaration. Well, I don't. I even checked the feed I have them: http://www.archaicchristianity.com/Feeds/rssforfeedburner.xml. It's fine. Both FF and IE parses it correctly, yet when I view the Feedburner feed I see those question marks. If this doesn't quit, I'm going to have to drop Feedburner.
