title: calling youtube player api loadPlaylist returns bad request error 400
body: <p>I was trying to call method loadPlaylist in a player instance create by new YT.Player() constructor, so according to the docs</p>
  
  <p><a href="https://developers.google.com/youtube/iframe_api_reference" rel="nofollow noreferrer">https://developers.google.com/youtube/iframe_api_reference</a></p>
  
  <p>I can pass a param called list with the id of a playlist or an array of video ids, if I try the playlist ID all works, but if I pass an array of videos ids, got the bad request error, I have checked the request url generated by the api</p>
  
  <p><a href="http://www.youtube.com/list_ajax?action_get_list=1&amp;style=xml&amp;list=UOoR27IF7Jk,j67Z9D0rs5s" rel="nofollow noreferrer">http://www.youtube.com/list_ajax?action_get_list=1&amp;style=xml&amp;list=UOoR27IF7Jk,j67Z9D0rs5s</a></p>
  
  <p>so the url is correct but is returning me the error, anybody know if I can't actually pass videos IDS and the docs are incorrect? and if so how can I create a playlist from the api?</p>
