Adam on "Creating a Podcast WITHOUT a Plugin"

I'll definitely follow the instructions on the Podcast page for outputting the link.

I use the Advanced Custom Fields plugin. Do these custom fields work the same as WP's native Custom Fields? I want to make sure I don't have to do something extra to get the MP3 link to work.

Would it be necessary for me to use a function to place the custom field in my RSS Feed? E.g. look at Tip #3 on this page:

Thanks for a super fast response!
