How do I download this to my Mac? Anyone give me simple instructions?
Get the desired video playing in Safari. Choose Activity from the Window menu. You'll see, in a new window, a list of every window and tab currently displayed in Safari with the different bits displayed on each page sublisted as well as their size. Find the line that is the video itself, usually the largest size listed there. Holding down both the command and option keys double click on that line and it will be downloaded to your default download location. Usually they can be played with QuickTime player from there. This works for most embedded videos on the web, although some sites manage to hide them in ways I've yet to overcome.
