Excellent demo Dez! Now let me try, here is a bunch of fly-bys of my Baby. (2:30 and 3;09 crack the barrier in front of the camera. )
It's working for me - try copying just the Youtube "Share" link, not the "Embed" link, and paste it to your reply.
I right click on the you tube video, then select copy video url , then paste directly in my post, It will not show up until I publish.
