While I a not a Penguin rep, I can answer your question, as I have enjoyed plenty of these lectures. Yes, shortly after the live lecture runs, you can access it at "My Penguin Magic" to either stream or download.
I prefer seeing the lectures live because I can Tweet questions, but lately I've been downloading them because the lengths (sometimes more than four hours!) often exceed my attention span.
