iTunes: old podcasts in error

I am trying to download all the Podcasts from iTunes. The list downloaded by iTunes contains 62 podcasts. I am able to download most of them, but some come back with errors: - brainstorming 1/2 - how to resign 2/3 - preparing for your review 2/2 - managing during mergers and acquisitions 2/2 - time to party? - answering questions in a presentation 1/2 - how to make a job offer 2/2 - how to run your staff meeting 1/2 - how to handle body odor - managing through a personal crisis - how to take notes Some of these I had already downloaded (and deleted). I know I can manually download each file and then import each file into iTunes, but I wanted to check if there isn't any easier solution. Help anyone? :-)
