Okay, so it isn’t new anymore, but it is still a good WordPress plugin for embedded YouTube videos (via GeekLimit):

If you’re interested in putting videos in Wordpress posts, [...] just head over toone [sic] of my personal favorite plugin guys, Viper007Bond, and download his Video Quicktags plugin. Same great functionality as my method, but with pretty buttons in the WYSIWYG editor!

While the buttons aren’t as pretty as we are led to believe, the functionality is great. Easy embedding of YouTube (and others) videos without having to turn off the WYSIWYG post editor in WordPress. Best of both worlds, baby!
