RSS feed options

I was using the PodPress plugin a while back and didn’t like it because of some changes it made to my RSS feed. I uninstalled PodPress and the feed didn’t go back to normal. A while later I then updated my wordpress to 2.5.1 and RSS feed still has the PodPress effects. Does anybody know how to reset my feed? My main beef with it right now is the author name is not what it used to be. If you view the feedburner feed the author doesn’t show up, but if you subscribe using a reader, you can see the author field and it doesn’t show the username of who posted (my blog is multi-author), it just shows one username.
