HotMovies has some hosted FLV trailers for specific movies. I've never been sure if trailers do a good job of selling VOD content, though. Maybe it does, but hasn't in my experience.
Though it's a bit of extra work, they offer a clip creator that builds your own hosted FLVs from most any of the movies they have available. You can take clips from any portion of the videos.
They do provide the FLVs in their own player, but you can always grab the URL to the FLV and link from your player.
