I shall pimp out the d20 Radio network. It is a group of people that put out podcasts for a variety of things. Some weekly, some semi-weekly and yet others are just whenever they can get the next episode done. The first one was the Order 66 podcast "the first podcast devoted to Star Wars Saga Edition". There are many others for Pathfinder, just about every edition of D&D, and more. There are also variety podcasts like the HP Podcraft Literary Podcast.
My personal favories are: Chronicles:The Pathfinder Podcast, Order 66, and the afore mentioned HP Podcraft Literary Podcast. All these and more can be found at d20radio.com. Of course what is a good network with out forums? d20radio.com/forums is where those can be found. Good luck to all and I hope the d20 Radio Network has a podcast for you.
