MIT has lots of courses up on youtube, including one on film:

Hitchcock is the primary topic of Lectures 9 & 10 but is discussed in passing in many others as you'd imagine. The Professor, David Thorburn, is never less than enthusiastic & interesting. He makes the odd amusing error (e.g., saying that Rusk in Frenzy is played by Caine!) but is otherwise pretty reliable I'd say. Psycho is briefly discussed but the two Hitchcocks the students watch in the course are Shadow of a Doubt & Rear Window.
p.s. It's the 50th anniv. of The Wild Bunch this year so books are blooming on the topic. Here's a review:
