Your episodes do not contain any playable media. The link and 'guid' tag for each episode lead to a web page with an embedded player; this won't work for iTunes. You need to have an 'enclosure' tag for each episode containing the URL of your media file, including its extension e.g. .mp3, and this must be a direct link, not an embedded player.
iTunes does not display episodes which have no media, which is why your feed is turning up empty there.
You need to sort this out in the original feed, then Feedburner will just follow it. WordPress causes a lot of difficulties in thie field, but I can't advise on how to use it. At the moment it is, as I say, producing an embedded player - what are your media files? They must be .mp4, .m4a., .mp4, .mov or .m4vfor iTunes, not Flash, WAV, or other non-compliant formats.
There is a WordPress plugin called Podpress which is specifically designed for podcasts, and which you might want to investigate.
First off, thanks so much Roger for sharing your knowledge here.
Ok, so I'm not sure why my feed isn't working:
I'm trying to publish my first episode, and it seems to me that everything is good. Here's the link to the media enclosure:
Yet I'm still getting the same "We had difficulty downloading episodes from your feed." error message.
Any help would be greatly appreciated!
Please start your own thread when you have a problem.
Your feed can be subscribed to manually in iTunes and works there; FeedValidator throws up some minor errors but nothing that I would have expected to upset the Store.
Your episode media file uses a Feedproxy link redirecting to the actual file; this may possibly be upsetting the Store though I've seen it work elsewhere - you could try using a direct link and seeing whether that helps.
