@ebimania: I wrote one js script my self and included it on a template .js file. This is it:

//Reset the content of the video player when selecting a video
//So that way the videos wont play two videos at a time

jQuery(function($) {
	$( document ).ready(function() {
	    $( ".videos" ).click(function() {
		  var originaldiv = $( ".item.active" );
		  var originalhtml = $( ".item.active" ).html();
		  originaldiv.html('');
		  originaldiv.html(originalhtml);
		});
	});
});

That is it!
@emarket-design: I dont think the problem is about plugins because your demo works the same way, playing two videos at the same time: https://ytshowcase.emdplugins.com/video-horizontal-slider-gallery/
