My episode is not playing in the store

Your feed is at http://feeds.feedburner.com/ConnectionswithCraigSherman

There are three items in your feed: only the third has a playable media file. This appears when subscribing but does not play in the Store within a reasonable time.

The URL of your file is a Google Feedproxy one and though it works OK in a browser it redirects to a Google Drive URL. Google Drive is not a suitable place to host your media files - it has consistently caused problems and I would advise you to find another host.

Your podcast is definitely called 'Connections with Craig Sherman':

I can't really offer much in the way of recommendations - my files are hosted on Godaddy and it's been fine. Any normal webspace will do, provided it handles 'byte range requests' (the method used by iPhones' - you should check with the supplier before committing. Free services are dubious as they offer limited bandwidth and storage, and like to add adverts to any web pages. You tend to get what you pay for.

That's nonsense. I have websites and around 200 audio files on GoDaddy without problems.I should just move the files there and amend the feed accordingly. The URLs in the feed must be absolute, not relative - i.e. they must include the http:// and the domain name. Don't change the 'guid' tags, then the change won't affect subscribers.
