I use the Podlove Podcast Publisher (http://wordpress.org/plugins/podlove-podcasting-plugin-for-wordpress/), which is alpha, but works on many sites, for example on the twenty fourteen theme. Before you fixed the media element problem I couldn´t visit any episode at all, which was created by this plugin – only a white site was shown.
Now I get a normal site back, but it seems, that your media element overrides the plugin media element. Could you please have a look at your media element implementation, because it looks very nasty at the moment?
