Finnish Broadcsting Company podcasts not working on Squeeezebox

I'm having problems listening the podcasts of the Finnish Broadcasting Company (YLE). Squeezebox can list the different episodes, but when I start to play any of them, the playback just stops right away.

Here's an example of the podcast RSS feed: http://feeds.yle.fi/areena/v1/series...nloadable=true

I would like to find out what's wrong in this and let the Finnish Broadcasting Company know it, so they could fix it (if the problem is in the podcast feed).

How to debug what's happening when the server is parsing the podcast?
