Should YouTube Videos be seen in the Course Preview mode

OK, I've followed the above instructions, and I can preview the video fine, but once I click "OK" then I'm dead in the water... just a black YouTube box with nothing that plays for 5 seconds. I've tried different variations on the long link trying to make this work... I've tried copying the long link from the link display box - same thing happens - I can preview, but get no further. I've even tried clicking the embedd button on YouTube and copy that entire code in the embed box and try with that I can't even preview it. I must be missing something. Other suggestions??
