Youtube Video Plugin format issue

Installed plugin and activated the Widget in the Footer position, to show a single video from a YouTube channel.

It displays fine and the page seems to display correctly ... however, if you scroll down, and keep scrolling, eventually you come to a bright RED video play icon ...

Not sure why or where this is coming from but it goes away if I disable the Widget.

The site is http://treasuredmemoriesscrapbooking.ca/blog/ and can be seen at the very bottom of the page.

I can send a screen shot but it is so far down it is just the Play Icon .. have to see it to understand what I am saying.

Thanks, probably an easy fix ... just not sure what is needed to resolve this ...
