Wordpress CSS Question

Hi guys,

I'm having some issues with a slider on the homepage of guitarmadeez.com. The 3rd slide is a video that should play and I can't get it to play for the life of me. It's just a solid color background. Any ideas?

I've tried 3 different computers and still don't see it. It's just a blank background when that slide rolls around. The following is the code I'm using which I had cut and pasted from the theme's shortcode guide:

-------------------------begin code---------------------

[ux_banner video_mp4="http://www.guitarmadeez.com/MumfordAndSonsBabelGuitarCover.mp4" video_ogg="" height="400px" link="" animation="fadeInRight" text_align="left" text_pos="left center" text_color="light" text_width="40%"]
Summer coming...

[button text="Shop women" link="http://flatsome.uxthemes.com/product-category/women/"]
[/ux_banner]


----------------------end code--------------------------


Any thoughts?

Any help would be appreciated,

Thanks!
