Click the link of the program to which you want to subscribe. This will take you to a page of encoded gibberish that a podcast application reads in order to download the correct audio to your computer or mp3 player. Copy the address of that page from your web browser's address bar and paste it into the subscription "feed address" of your podcast application. You will need to have an application such as iPodder or iTunes on your computer in order to listen to podcasts.
