This is what I recommend. For every item, there's a <description>. You will want to add a media link to the enclosure URL into the description of each item.
e.g. before: <description>Sunday July 3, 2005 Worship Service</description>
after: <description>Sunday July 3, 2005 Worship Service <a href="
http://newbergfriends.org/nfcmedia/2005/NFC_July_3_2005.mp3">Download</a></description>
I created the content within the description using this resource:
http://www.tools4noobs.com/online_php_functions/htmlspecialchars/I pasted in pasted in: Sunday July 3, 2005 Worship Service <a href="
http://newbergfriends.org/nfcmedia/2005/NFC_July_3_2005.mp3">Download</a>
It gave me: Sunday July 3, 2005 Worship Service <a href="
http://newbergfriends.org/nfcmedia/2005/NFC_July_3_2005.mp3">Download</a>Once you have all your media linked in some form in your <descriptions> of each item, then you can use the RSS2 feed import tool built into WordPress (it's a plugin you install when you navigate into the import section of WordPress, it's part of WordPress.org).
Then, once your posts are imported, go to PowerPress Tools > Import from other blogging platform (like Blogger, Movable Type, etc...), it will show all your media files with options to import them as podcast episodes, detect the file size and duration, etc... Once you do this migration, you're done.
We do this stuff quite often for clients, we have scripts that automate the process of putting the links into the description. So if you get frustrated or want to hand this off to someone else, feel free to
