Podcasting is a new way to broadcast media content over the web; when an author publishes an episode, podcast suscribers are informed, through an XML feed. (Copied from Rhythmbox Docs & edited slightly - is it too technical? XML?)
Banshee allows you to subscribe to a feed so that when a new episode is published, you are notified and it downloads automatically.
Tip: You can only subscribe to Podcasts when the Podcast Extension is enabled (it is by default). See Extensions
To go into Podcast view, click on Podcasts in the sidebar.
