George,
I'm really not sure what we can do about that
iTune is such an ugly beast to use at the back end (
think: people that wear rubber gloves and help rhinos give birth uuuuugly) - but as Atrayo says, there's a direct link to each podcast. You will always find this link in the first reply with the podcast information, and then you can listen to it on any player you like, or transfer it over to your iPod/MP3 player.
