I'd have to side with Asseroo's second statement, Vimeo.
I've been using Vimeo on my personal website for some time now, and the web is littered with examples of it working perfectly. Off the top of my head, check out http://www.roulette.co.uk/casinos/supercasino/
These guys have fitted it right into their design. I may be a bit late too, but i'm pretty sure the YouTube ones are really clunky and chunky! good luck!
