In our site, we had 7 episodes published as wordpress posts and as per your advice on one of the forum discussions we installed a post type switcher and changed to podcasts. Those podcasts work well, but for some reason posting a new podcast is giving some sort of error. It automatically renames the post "Click to download *actual post topic*" and shows an empty page with fatal error saying it couldn't be parsed. I know it claims to be a theme problem but maybe you know what is wrong with it... here's a link
The one with the problem is episode 8.
