Blocked background video in mobile css

Hi,
is possible blocked a JUX Background Video module in mobile template or blocked a slideshow position in mobile?
Because if I go to web on mobile phone there is a lot of free space before main web.
My web: xboxplay.cz , I use nozix template.

Thank you for help

This not
In PC browser I want video background .... Only in mobile phone I want blocked. Maybe solution is blocked position - SLIDESHOW in mobile phone css .... Is it possible? But I don´t know where

No, still is there


but now is another problem, if I add youtube video - save it ... is all OK,
but if I open background module again - video playlist is gone
