Oh dear, a zealot. And an ill-informed one at that. Yes, if the gallery
gave me a free pair of NIKE shoes to wear. By the way, in English one
is 'in' shoes, not 'on' them. YouTube uses the flv (Flash Video)
format. By various methods, including getting a Firefox addon, you can
download the videos to your hard drive and convert them to mpegs with
free software such as ffmpeg.

Google Video is even easier. After completely viewing a video, it will
be in a folder on your hard drive, as a file with a .gvi extension. It
is actually in DivX format. Change the extension from .gvi to .avi and
it's a perfectly normal mpeg4 file.
