Okay, here are the general steps of what you need to do:
1. You have your 2 podcast episodes. Great. Are they at a bit rate that makes the file a reasonable size for download? If they aren't, you need to tweak them in you audio applications until they are. Also, if you want to add artwork to your podcast, you need to open your file in iTunes and modify the ID3 tags. More info
here.
2. You need to find a host for your files, like Libsyn . . . or, some blogging services also offer server space, if you already have a blog.
Here's a decent article on the subject.
3. You need to upload your media files to your web host, and create an RSS feed so that people can find them. Creating a feed can sometimes be confusing - you can use a podcast generator (they are all over the web) or you can build the feed yourself. iWeb can also help you set up one, but iWeb can be difficult to navigate if you want to change your feed around later.
Here's a basic tutorial on building a feed. Also, you should check out the Podcast
Tech Specs, the
FAQ, and the top 6 podcasting questions (sticky at the top of this forum).
4. After your RSS feed has been built, you need to check that it is valid. Run it through
feed validator and then use the "Advanced -> subscribe to podcast" menu in your iTunes player to test it out.
5. Once your podcast has had all the bugs worked out and runs like a well-oiled machine (and you are happy with the URL where it resides), you have many options. If you want to use
FeedBurner to count your subscribers, you need to set yourself up with them before you do anything else, however (because you will need their URL to submit to directories). But, if you don't feel the need to do that, you can start submitting your feed URL to any directories you want your podcast listed in . . .such as the iTunes Store, Podcast Alley, Podcast Pickle, etc.
If any of these steps are confusing to you, ask before you leap. Otherwise have fun and good luck!
