I'm afraid I know nothing about recordings of previous events. I suggest you contact Heike or one of the other organisers about that. This time I plan to do something very similar, but take more time to do it! There didn't seem to be much interest in going off and playing with Moodle while I was online last time, so I shall use the extra time this gives me to look at some things in more detail.
I don't know how long it will take to get the recording up, but I would think Heike and her team are still a bit busy. I would give it a day or two and then contact Heike if it doesn't appear.
All the best,
