David,
Check out our recent episode on Podcasting with Buzzsprout. Buzzsprout handles a lot of the mechanics of getting your podcast published, and provides a simple HTML widget to embed into your HTML pages. Sounds like it might be a good match for your needs.

Our young pastor has decided our aging, small, country church needs a podcasting feature on our website. With my limited knowledge of basic html, I found the open source Podcast Generator and plodded on. God guided me through an intense and difficult encounter with stuff called PHP. After about 2 weeks of trial and error, I finally have what I need.(http://www.collegegrovemethodist.com/mp3/) Unfortunately, I need this to be on a html page on site. Could someone please help me????
