Unity video section

Hi,
The video.unity3d.com section is full with very interesting videos.
Problem is that it takes forever to start. Also there is a big lag if you try to move ahead the timeline.
I would greatly appreciate if unity could post / cross-post videos in the youtube / vimeo / whatever video service can deliver fast.
What do other people think about this ?

I prefer Vimeo or any service that allow them to be downloaded without streaming.

+1.Go for Youtube.
