RSS - problems with publishing and publish preview


I have been attempting to make an RSS content type and associated template to gather the latest 10 articles and publish it out as an rss file.

While the template previews as expected, when I change to authtype=101 then al of the articles disappear even though they are all of public status.

Perhaps related to that issue when I attempt to publish an RSS item I instantly get a publishing error:

<?xml version=“1.0” encoding=“utf-8” ?>

Any suggestions?
