One from Joost [HD]:
and one from the lovely Vimeo:
Quantum of Solace Trailer Text from Robert Holtby on Vimeo.
Vimeo is more kinda social network and has some funny videos.
Joost is more for artist's original videos and music in a decent quality [not-youtube]
Youtube is [an infinite] database of videos.
I use the 3 for different aspects you choose whatever u like most
