Strange Podcast Behaviour

A friend has just contacted me about your Podcasts that are kept on
Neither of us can get any of the old Brainwashed Podcasts only the current one.
We have both tried to grab the ones listed here :
with no luck. The RSS feed only lists two Podcasts, Kranky and the most recent
Do you know if there a problem with their site? Do we both need ipodder
software to get them? iTunes only gets the most recent one

We only host one Podcast at a time usually for a number of reasons: server space and traffic being probably the biggest.  If you miss one, then subscribe and you won't miss another.
