Themify.me Sucu – Slider problem

Hi there,

It’s my first time posting here. I wonder if someone can please help? My current knowledge of WordPress code is not extensive; this is a blog I’m creating from a Themify.me ‘Sucu’ theme.
http://www.makemoneyonlineareality.com and here is the demo which looks like this:
http://themify.me/demo/#theme=suco

The video facility within the slider does not seem to work (if it’s the settings I don’t know what the correct settings should be), and I don’t know where to go from here and don’t know what the problem could be. I could easily change the theme to not include the slider but I like the one that is there. It could be something really simple, but if somebody could guide me I’d very much appreciate it.

I await your expertise – thankyou.
