FEEDBURNER AND WORDPRESS – rocky marriage

I can’t validate my feed on feedburner. Now, I’ve spoken with Feedburner support several times and they say its a WordPress problem. Now, I’ve already spent numerous hours trouble shooting this, so I’ll let you know the situation:

I receive the following errors:

http://tatenova.com/queerfilm/?feed=rss2 is returning a 404 Not Found from your server

http://tatenova.com/queerfilm/?feed=rss has a validation issue (the first line of the page is blank and as a result won’t validate as valid RSS)…

http://tatenova.com/queerfilm/?feed=atom has the same validation issue (the first line of the page is blank and as a result won’t validate as valid RSS)…

I’ve reinstalled the wp- etc files, I’ve tried using different themes, I’ve used Fetch and a manual FTP to see if it’s the FTP that is adding the spaces, I’ve contacted feed burner who told me the following:

At this point the site is working for me, but the feed address

http://tatenova.com/queerfilm/?feed=rss2

seems to redirect to

http://tatenova.com/queerfilm/rss.php

Please help. Thank you,
