A bit bulky. I like how that big fat bar doesn't appear when the video's playing. Search reappears if you hit the little data button in the lower right-hand corner (the one that lets you gank the link or embed code), as well as when the video is paused.
Like with Hulu (didn't I tell you that was a sassy feature? I totally said that), query results appear inside the embed window. (That means you won't be redirected to YouTube if you run a search.) You can sift through search results, click on videos and watch them without leaving the site you're on.
