Loop youtube video in multimedia collage in Dawn Theme

[ebon]

How can I loop or return to start a youtube video clip in the multimedia section in the Dawn Theme to avoid youtube display other clips once mine is done.

Its only a 14 second clip so is it possible to upload the clip into the theme or shopify itself?

open to suggestions.

url is preacha.com 

the section in question is third section down on the front page. 

thank you
