U.C. Berkeley has a couple of professors that do a weekly radio show called Berkeley Groks, which they also release as a podcast. It's a fun show, even if a bit nerdy. This week they interviewed Matthew Chapman, the great-great grandson of Charles Darwin, on evolution vs ID. It was a good show, it could have easily gone on for another hour quite comfortably, and the podcast can be streamed or downloaded, in multiple formats, here:

It is kind of nice to hear someone speak about it in a friendly interview format, rather than a debate, where the ideas can be explained without being on the defensive.
