On my mission for the remaining Star Trek Voyager clips, I tried searching on Google Video. When I clicked onto the TV Show category, I found it was swamped by a single chat show at 99¢ a video. It seems that this new searchable medium has some way to go before it starts to become useful.
After no success with Voyager, I went onto the Popular category. There a brilliant French clip about a hidden-cam egg factory, a really dodgy Russian road tunnel, a gaseous American preacher and some other stuff. After a while the “Popular” videos appeared again and again. Have a look for yourself at: video.google.com.
