Videos not rendering (or being embedded)

I have tracked the problem down to `_video_embed_youku_get_video_id` which is not returning an ID. The URL being passed in is `http://v.youku.com/v_show/id_XMTQwMjA1OTMwNA` and the regular expression is not able to properly parse it.

I'm not good with regular expressions, so I've rewritten that function to use parse_url (since it was in an inline code-comment in there anyway).

function _video_embed_youku_get_video_id($url) {
  $id = FALSE;
  // Parse_url is an easy way to break a url into its components.
  $parsed = parse_url($url);
  $path = $parsed['path'];
  $parts = explode('/', $path);
  foreach ($parts as $part) {
    if (strstr($part, 'id_')) {
      $id = str_replace('id_', '', $part);
      return $id;
    }
  }

  return $id;
}
