Oh, I've visited a cryptolecture a few weeks back, I believe they have recorded and uploaded it up to Youtube.
It seems so potential, I'd like you to pm it for me!
I only know that they did upload it, but where or how to find it I have no clue. On top of that, you should try and find a cryptolecture in your area, it's much more useful if you have the ability to ask your lecturer questions!
