I don't use iTunes to collect my podcasts. Instead I use
Google Reader. If you already have an account with Google (gmail, wave, calendar, docs, etc) you can use that username and password to sign in. If not it is free. Just add a subscription to the following RSS address:
http://www.wdwinfo.com/podcast/unplugged.xml
Whenever there is a thread about not getting the podcast I can always get it from this address. The DIS may use feedburner for their iTunes feed, I'm not sure. If they do feedburner had a couple of issues last week.
