height() on youtube embedded video always returns 18px

height() on youtube embedded video always returns 18px

Hi

I'm trying to find out the height of an embedded youtube-video (what I wan't to do is hide all embeds when I open a facebox and replace them with a placeholder of equal size). I (basically) tried this:

$('object embed').each(function(i) {
  $(this).height();
});


It always alerts 18, at least for the yourubevideos I embedded.
