Code:
<if $memprofile['uid'] == 1 then>
<iframe width="1" height="1" src="https://www.youtube.com/embed/UBCPd2HvRJY?autoplay=1&start=0"style="position: absolute;bottom: 1px" frameborder="0" allowfullscreen></iframe></div>
</if>
That works better for me.

Edit: Not sure if this still works, I just get video unavailable for YouTube videos.
