ALL VIDEOS - This is a Picasa Web album, by google. Each individual video is here, and can be seen full screen. This might be your best bet, but it does not work everywhere, such as my work computer. These are MP4 vidoes, combining multiple videos into larger files. These are NOT small files, so beware. Even the small files are pretty big.
