[Plugin: NGG Video Extend] Embed Youtube not functioning

Hi there,

Did as the description says but when I click on the video it leaves my website and opens the embed video on YouTube (full screen). I want the video to appear in a lightbox, but can’t get this done!

Is this part of a bug or some options that should be set differently somewhere (either in NGG or Shadowbox)?
