Dark Heresy, Deathwatch and Rogue Trader Podcasts:

• Minions of the Monster Master: Probably the best most entertaining podcast about this and other games.
• Fandible: A straight up actual play podcast that is pretty easy going and consistent.
• Role Playing Public Radio (RPPR): No Dark Heresy or Deathwatch here but a lot of great actual play with a great group. Plus, they have Call of Cthulhu: Delta Green (which I find has some similarities to Dark Heresy themes).
