Yeah, I saw it.
I can't see any reason for that at all and basically avi is not ment for the web, swf is a terrible format to compress video to and not logical, and wmv is also just not very good compression and plays in windows media player, which is not only awful but something mac users often have trouble with. there is a reason .mov, mpeg4, and h.264 are so popular and its because there good proffesional compression options for the web....so thats what I use. If they dont like that, o well. the video plays fine so theres no reason not to use it.
