yes it is very easy. first of all you need mozilla firefox, then you need video download helper. then after you install that you need to download the
video download helper converter to convert eveything to avi.
I expect (not sure) that the browser will save it to a temporary location (it does in linux, not sure about windows) while you watch it. Just find
that location, find the video and copy it, since the browser will delete the original when you navigate away from the page.
Simple as that, no need for external software except the player.
