Easy steps to create a Podcast
Setting up the parameters
Title: The title of your podcast. Will be shown everywhere.
Description: A description of your feed. iTunes shows this in the iTunes Store as (surprise!) description of your feed.
Copyright: iTunes shows this below the Logo in the Store
Channel Author and Email: Not really shown anywhere in iTunes, but it's published in the actual feed. Some readers may show it.
Limit Text: Will limit the description to the count of words set in Text Length. For iTunes descriptions the text will always be limited.
iTunes: Keywords: Keywords for which can be searched in iTunes Store. Maximal 12 words are allowed and they need to be separated by comas
iTunes: Subtitle: The contents of this tag are shown in the Description column in iTunes. The subtitle displays best if it is only a few words long.
iTunes: Image: The podcast logo
iTunes: Category: The iTunes Store is organized with categories, which can be set here. Choose a fittin one.
iTunes: Owner: This tag contains information that will be used to contact the owner of the podcast for communication specifically about their podcast. It will not be publicly displayed. Except that it is contained in the raw feed data of course.
iTunes: Language: Accepted values are those in the ISO 639-1 Alpha-2 list (two-letter language codes, some with possible modifiers, such as "en-us").
iTunes: Redirect: This is only used if you want to forward your podcast to a new location. Leave this empty if you don't need this.
Enable the Sermons for Podcast
Make sure the needed sermons are flagged for the podcast in the Sermon Manager.
Offer a link to the Podcast
Your podcast is now already functional, but the users need to find it. So you should publish a link to the podcast.
One way is to use the SermonCast module. It will offer an iTunes link and an RSS link. Basically it's the same link with a different prefix. It also allows additional text to be shown as well as a link to a help page.
The default settings of the module will work, however you can adjust it to your liking.
Another way would be to create a menu entry for the podcast view.
Or you could just offer a link in the content somewhere, the link will look like this:
http://www.sermonspeaker.net/index.php?option=com_sermonspeaker&view=feed
Submitting the Podcast to the iTunes Store
After you have verified that your podcast is working, you may submit it to the iTunes Store. To do this I'll suggest you read the guide from Apple itself:

A note about the Podcast URL
One thing to remember: A Podcast URL should never change, or it will break for the existing subscribers. This is the reason why the SermonCast module generates an URL without SEF. SEF URLs may change if you ever change the alias for a specific menu entry, which will break Podcasts.
So if you submit a Podcast to the iTunes Store, use the non SEF URL to do so. It may look more cluttered but is much more failproof
