Podcasting feedburn

OK. I'm trying to get a rudimentary podcasting feed operational. I think if you use this one: http://feeds.feedburner.com/turksheadreview, you should be in good shape. With the new version of iTunes, for example, you can go to the Advanced menu and select "Subscribe to Podcast", paste the URL above, and it should find any new linked mp3 files. Looks like the server I'm on isn't configured for recognizing m4a files, so I'll probably use mp3 for podcasting. I'm new to this, so patience would be the order of the day....
