The SAR 3D tutorial is experiencing an error message when attempting to load the video. It is stating “video cannot be played because the file is corrupt”. It was functional before the Spring 2016 CERT class started. I don’t think it has anything to do with the announcement that Apple will no longer support QuickTime for Windows (article) since at least one person was accessing with a Mac.
I have a back up copy that I will upload and see if that fixes the issue.
