I like the following video, because it is short, simple and hits on many of the CalgCamb Guide skills.

I've also attached a few articles looking at the impact of communication / patient-centered skills on health outcomes (the residents love that stuff), and I find the gp.net site (from teh UK), the best 'one stop shop' for any Calgary Cambridge resources. 

Hope that helps,
