Awesome!! I was wrangling with this exact same issue. Changing the “name” field to something else fixed it.
For future reference, I was able to exclude a category while still using FeedBurner. I just edited the FeedBurner source feed to be:
http://your.site.com/index.php?feed=rss2&cat=-N
(where N is the category number to exclude)
It’s looking good so far. If I run into any problems, I’ll post back here.
