Well technically is not download at all, because in some places they might have firewall or will reject any request. But here is the best method: Download any screen record software like Snagit and use their 30 days free trial. Resize your browser so the video has the best size and resolution. Then just open Snagit, Select area to Record, and start recording. You can always open the video and edit it to Camtasia, or other video editor. Hope this works for you as it does for me.
