thanks for your help.
what should i use to get a video in the lightbox?
<div id="test-popup">
<iframe src="http://www.youtube.com/embed/Gb1HHsreEgQ"
width="560" height="315" frameborder="0" allowfullscreen>
</iframe>
</div>this seems to work, but looking at your examples it looks like you use intenseVideocontainer, but i can only find video and fullscreen video.
