Everybody knows how insightful are David Ben-Zvi talks (and comments/answers here on mathoverflow). I was trying to watch the [LMS 2007 Lecture Series on Geometric Langlands](http://www.ma.utexas.edu/users/benzvi/GRASP/Oxford.html) by David, supposedly made available via [GRASP Lectures](https://www.ma.utexas.edu/users/benzvi/GRASP.html), but the server is down or no longer exists. 


Some of the GRASP lectures are available on the iTunes Podcasts of the University of Texas Austin, but unfortunately not these ones. 


Does anybody know where else to find them online or did anyone downloaded them back then and could, please, make them available to the community again?



LMS Lectures on Geometric Langlands
The videos from the LMS lectures and all of the GRASP videos are now available again from the links you gave (for download, not streaming). Many apologies for their long hiatus offline and many thanks for your enthusiasm and persistence!! Please do email me for broken links etc., and I will update the site with some more recent materials.


Edit June 2022: The links have moved, the GRASP videos (including the LMS lectures) are [available for download here.](https://media.ma.utexas.edu/video/GRASP/streaming-server/math-grasp/)


While we're at it (and to compensate for these lectures being such a pain to track down), here is a link (hopefully even a working one?!?) to videos of my entire Spring 2021 graduate course [From Maxwell to Langlands](https://utexas.hosted.panopto.com/Panopto/Pages/Sessions/List.aspx?folderID=60f2affd-9683-4426-8552-acb300082333) (or some name to that effect) about the Langlands program and electric-magnetic duality. Notes for these lectures are available from [Arun Debray](https://www.math.purdue.edu/~adebray/lecture_notes/) and [Jackson Van Dyke](https://web.ma.utexas.edu/users/vandyke/) (and the dream is to eventually turn these into a book, but I wouldn't hold my breath).
