is there any good resource for video lectures of differential geometry?

Clay Mathematics Institute 2005 Summer School on Ricci Flow, 3 Manifolds And Geometry generously provided video recordings of the lectures that are extremely useful for differential geometry students.

In fact, MSRI Online Videos is enormous, and their archive has some interesting parts [for DG students] (not quite sure if they still work, though).

I am not mentioning Youtube here but if you are interested in elementary topics you may find some useful videos there.


A rather late answer, but for anyone finding this via search: MSRI is currently (Spring 2016) hosting a program on Differential Geometry that has/will have extensive video of all lectures given in the related workshops (Connections for Women, Introductory Workshop on Modern Riemannian Geometry, Kähler Geometry, Einstein Metrics, and Generalizations, and Geometric Flows in Riemannian and Complex Geometry). Scroll down to the schedule at the bottom of the page, click through to the workshop pages, and you will see a video link to watch each talk listed.
