Well, I started watching the on-going series of lectures which I’d linked to a couple of blogposts ago. Frankly I can’t say the early lectures are at all good, and can’t now recommend you try them. They all seem, to put it kindly, very underprepared, underpowered, undercooked, low in nutritious content! Maybe later lectures are better.
I’d say more, but I’m saved the effort because there’s now a long comment to that earlier post sent by Peter F. which well expresses some of my concerns about the whole thing.
