It looks like they have lots of discussions posted on-line

You can find them on iTunes - which then can be automatically downloaded

They are also setting up an additional podcast called PRESENT MOMENT - which will focus on mindfulness and science - also through iTunes

another point.  the secular buddhists are focused on serious Dharma practice and most of the podcasts are related to that.. and not just mindfulness / meditation, but much more in-depth discussions on all aspects of practice, behavior, livelihood, and so on.
