You have to see, at the very least, a portion of the video to know
you want to download it. And some videos, you don't want to download: you
just want to view it on the web page and then then close the tab and be
done with it. In other cases, you might wish to view a video and comment
about it on the web page, or add it to your favourites, rate it, etc.
The idea is that you download the video, you watch it, then you delete it.
