Could you do a video about Playing Arkham Horror? Maybe not the whole session, but certainly the setup, and perhaps a bit of tutorial, and then if you're recording the whole session maybe just clips of some of the more entertaining moments?
Also, have you made an RPPR commercial? A clip with footage of Podcasts being recorded, games being played, and assorted candid moments of the RPPR guys with poignantly chosen background music and voice overs that promotes the site and its products?
