content retrieval recipe

[Torx]

unable to get content (only article headings) from http://feeds.feedburner.com/universetoday/pYdq

read tutorials, googled & api documentation. how about get_feeds ?
feedburner links to original article tried using "get_article" maybe its syntax?
it doesn't appear that login is necessary because i can click from feedburner and link to articles.

using: Ubuntu 10.04 LTS / Kindle-3 / 7.33 calibre-recipe / Python / .Mobi
