Podcast empty on Apple-Podcast-app but feed isn't

You have fallen over an interesting incompatibility in XML. The Store page shows episodes 27 to 65; when looked at in a browser the feed shows episodes 27-54, and when subscribing in iTunes the podcast appears to be empty.

This is because of a line in the 'itunes:summary' tag for episode 55, which reads

06. Howling - Signs (Rødåd Remix)

Now if you were constructing a web page, that would be perfectly valid, and would come out as

06. Howling - Signs (Rødåd Remix)

Indeed the iTunes Store shows this correctly in the summary, and so is not fazed by what is actually an error (though one would have expected it to be). This error is causing the browser I checked the feed in to fall over at that point, but has rendered the entire feed unreadable in iTunes.

XML is picky, and you need to use the numbered entities, not the named ones, so that to be correct your line should read

06. Howling - Signs (Rødåd Remix)

Alternatively you may be able to enter the characters directly without using the coding.If you change that line and re-upload the feed it should work immediately when subscribing.

Quoting from the Apple Help page http://www.apple.com/itunes/podcasts/specs.html :

There are five characters which must be entered using the named identity in XML:

All other characters can be entered directly in an editor that supports UTF-8.

However, you can also use numeric character references that specify the Unicode for the character, for example:
