I have just started experiencing a problem with some of my podcasts on itunes. Recently more and more are getting these exclamation marks, and when I click on it it says that the connection to network could not be made. I have tried deleting/unsubscribing and re-subscribing to get it to work again but it does not help. The only thing that works is when I press teh arrow button and manually download the newest episodes. I am using the latest iTunes 8.1.1. Can someone offer some suggestions to fix this as I primarily use iTunes for podcasts.
