Itunes and podcasts question

[Scott Ford]

Hello Folks,
	I am having trouble expanding podcast list in Itunes and downloading  
them.  I have subscribed to several podcasts and their first one  
downloaded.  I cannot expand the list of podcasts.  I have another  
podcast that is always expanded, however it has podcasts that I cannot  
figure out how download.  I have explored the sources table and there  
is not a download item.  I have changed the settings for the podcast  
reducing it to every hour and making sure to keep all podcasts.  I am  
a little stumped here.  Thanks for any advice..
