This is the method I like best. Uses jQuery FYI.

var player = {
    playVideo: function(container, videoId) {
        if (typeof(YT) == 'undefined' || typeof(YT.Player) == 'undefined') {
            window.onYouTubePlayerAPIReady = function() {
                player.loadPlayer(container, videoId);
            };
            $.getScript('//www.youtube.com/player_api');
        } else {
            player.loadPlayer(container, videoId);
        }
    },
    loadPlayer: function(container, videoId) {
        window.myPlayer = new YT.Player(container, {
            playerVars: {
                modestbranding: 1,
                rel: 0,
                showinfo: 0,
                autoplay: 1
            },
            height: 200,
            width: 200,
            videoId: videoId,
            events: {
                'onStateChange': onPlayerStateChange
            }
        });
    }
};

var containerId = 'ytplayer';
var videoId = 'abc123';
player.playVideo(containerId, videoId);
