How does one save a video from Youtube to one's hard drive for viewing at one's leisure? I am, of course, thinking purely in terms of being able to watch videos when I am offline, and not in any way thinking of bagging a copy of disco-dancing Sacred Band of Thebes before someone slaps a cease-and-desist notice on a parody musicvid.
