By " it doesn't contain proper formatting itself" I mean following:
When Oxwall looks up what is under the RSS URL you are using, it looks up under following URL:
http://feeds.feedburner.com/co/ioBp?format=xml
And here is what we see under this URL:
The XML generated by feedburner doesn't have the formating added originally.
I suspect that the issue is within the XML structure.
Here is the current XML structure of your feed. I have bolded where <description> ...</description> starts and ends. And as you can see the description is in plain text format. And that is what Oxwall takes- plain text.
After description ends,
<content:encoded> part starts, where all the styles are written, and Oxwall ignores this part since system just doesn't know what to do with this code:
<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" media="screen" href="/~d/styles/rss2full.xsl"?><?xml-stylesheet type="text/css" media="screen" href="http://feeds.feedburner.com/~d/styles/itemcontent.css"?><rss xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:slash="http://purl.org/rss/1.0/modules/slash/" version="2.0">
