a 910 KB ogg video, converted to divx encoded avi with the sound issue fixed so it has sound..
6.5 MB
this creates a real quandry, make it as easy as possible for someone to view a video tutorial by using a format they don’t need to do anything other than open the video, or save tons of data transfer and use the smaller file size, where the audio support is spotty in the plugins to support it for them.
edit to add:

the test video links are the same video file, a round of KNetwalk. the only sound is the clicking of the mouse and from the game itself.. one word.
but both have the sounds.
