The Scope of Google Video

When I go to the Google Video support page ( http://video.google.com/support/ ), it gives the following scope for the service:

"The Video index is comprised of videos that people have added using Google’s services (You Tube, Google Video) as well as videos from other third-party sites."

Where are the videos from the third-party sites? I personally have never seen videos from any site except You Tube and Google video (though I have been using it since the feature was introduced), even when I know that these other sites exist and offer a particular video. Popular video sites such as www.crunchyroll.com and www.veoh.com don't seem to be indexed at all in Google Video.

Google Image search trolls the web for images embedded on an seemingly impossibly wide variety of web sites. Why is the scope of Google Video so comparatively limited? Google Video would be a better search engine if it could actually be used to search for videos on all of the web. As it is now, to look for a particular video, I have to go to each of the video sites and search.

If they are concerned with copyrighting, why are they not concerned with copyrighted images?

Despite it's limitations, I prefer watching videos on Google Video when they are available because those videos that are actually Google videos (and not you tube videos indexed on Google Video) are higher quality and are not generally separated into many parts the way that videos on you tube or crunchy roll tend to be.

Does anyone know of a site that searches for videos the way Google searches the web?
