Click on link, wait for the "Continue as free user" (usually takes 1 to 5 seconds), click, wait for next screen, use the smaller 'arrow' and not the large square that says 'watch now'/'download'.
I'm sorry, but there are always pop-ups and some adds are NSFW. ;)
I do NOT recommend downloadloading, I've never done that from these sites before, so if you do, that is at your own risk. :) (I assume it's safe, but I haven't take the chance yet.)
