I've been playing around with different ways of hosting HD video - Youtube is fine, but is always low resolution. Google allows slightly higher rez, but not much, and posting video is a royal hassle. I also investigated Veoh - nice, they serve a low rez version, but allow you to upload and download the full resolution version... but they much with the aspect ratio, making your video look squashed.
DivX Stage6 is painful in that if forces you to convert your video to DivX, and forces the viewer to download the divx player - BUT it works, and is fast. Result? See below:
