Last fall PBS put on a 4 hour show about the existence of God. The link below will take you to a page with a bunch of clips and transcripts from the show. Basically the subject of the existence of God is discussed through the life stories of Sigmund Freud and C.S. Lewis. There are biographical clips for each man and well as a couple of round table discussions.
I think interesting PBS show might be an oxymoron but this one was put together well and fair-minded about the question.
