I have just joined and was in a similar position. It is not easy to get the information you really need. I tried PodcastAddict but could not get it to find the members only feed. So I have just tried DoggCatcher and that worked, though it was a bit fiddly. I chose Subscribe from the menu Then Advanced. Then choose Feed RSS URL. in the entry box where it says http:// (which you ignore) type
and then tap OK. That did it for me and I am connected now. I have only just got it working so I can’t tell you how good DoggCatcher is otherwise, but it was easy to load up the episodes so I am hopeful it will do what I need.
Hope this helps
