This CSS tweak will add a vertical scroll bar to your Video Module on the home page. If you only have 2
videos selected, the bar may not show up with 300 height. You can adjust the height to suit your preference. NOTE: THIS IS NOT FOR VIDEO PLAYER, BUT FOR LIST OF VIDEOS.

Add this CSS to Manage/Appearance/Advanced CSS, at bottom.

/* Scroll Bar for Videos */
.xg_widget_main .module_video .xg_module_body {height: 300px;overflow : auto;position:relative;}

To scroll through Videos on Member Profiles too, just remove the main page class, like this:
.module_video .xg_module_body {height: 300px;overflow : auto;position:relative;}
