They don't really get going until 15 minutes in. They talk about afterlife decision making and consider it analogous to Pascal's wager.
She brings up Homer Simpson's view that being neutral about religion won't tick off God as much as choosing the wrong religion. Simpson's view is atypical and is to bring humor into the show, but she finds it useful as a prop to discuss Pascal's wager.
So I watch from 15 to minute 17 then skip to 30:30. She emphasizes that the question is about the probability of what God should be expected to be like, because you are not choosing between belief and God or not God but in which religion. She says (and he somewhat agrees) that if being a good person has no impact on the question of whether you are likely to be rewarded positively, then being an atheist or a theist has the same mathematical expected value (50/50). At 56:00 she's saying that you could try to imagine that if God exists you could try to work out the likely characteristics of God. He's saying (opposite) that without empirical evidence (as opposed to philosophical reasoning) it would not matter, because you would not know enough to factor into the probability. I think she is saying that there is a slight sense to trying to work out God's characteristics, while he is saying there is no point in doing so.
I won't preface this with anything, other than the fact that this discussion was genuinely interesting to me, and is one of the few discussions that I have seen where the theist actually made me think. I don't think it's at all likely that any gods exist, but perhaps Dr. Jackson made a good argument for religious participation in the religion one sees to be most probable.
Pascal's Wager was never very good. In a world where we are pressured to behave like we have all kinds of belief and strong faith it is a small comfort, but any person that wants to believe it can and any that doesn't can dismiss it. That pressure is unyielding throughout every age and in every culture that I have heard of. There is just a way that people want us to be, words they want to hear us say, confirmations and affirmations. I think this is Pascal showing the cracks in his feelings about faith. There is too much pressure to have more faith than we can produce.
For a long time there were creationist arguments, but those have changed or are going away. There is nothing to stand on except a choice to believe, a strong desire to see loved ones again, a feeling that someone is watching us, a longing for another time etc. We no longer have the comfort of the authorities we once did.
