Although I still have not figured out how to display all the posts on one page,
I used this code to solve my problem:
<div style=”text-align:center;”>
<?php posts_nav_link(‘ · ‘, ‘previous page’, ‘next page’); ?>
</div>
When placed in the archive-podcast.php within Seriously Simple Podcasting plugin,
it enables you to see older and newer posts.
Thanks,
Drew
