You can see how we to it at my church--I have two displays of the podcast going, using Joomla's newsfeed component.
1.) On the front page of
listeningtohope.com, we have the most recent 5 sermons showing, with descriptions.
2.) At
hope.org, click on "Bulletin" at the top-right. This opens a box at the top of the page. The left side of the box is a display of the most recent 5 sermons. Space is tight, so I'm just displaying the title/link--no description.
Note: The number of entries to display is controlled by the settings in the newsfeed component. So is the "show the description" setting.
