Sorry but since it's crossposted I think you should try the Apple forum which has the most folk on this topic.
I've seen there is no way to manually delete podcast in Itunes 11.4.0. In fact I have found many people frustrated with the new version and wanting to revert to 10.7. My question is just how are podcast supposed to get deleted in 11.4?? There must be a way to get rid of old ones. I thought that if they were marked played that got rid of them, but no. Anyone have any suggestions or where I could get info on this process?
