I have tested your Windows 7 + IE 11 and confirmed the YouTube videos don't have the prev/next navigation arrows like in non-IE browsers.
The issue is with flash (for more information, see "wmode" at http://helpx.adobe.c...onal_attributes ).
I'd assume that if you have flash disabled in IE and instead the HTML5 fallback player gets used, the issue wouldn't be present anymore.
Cool Carousel uses the PageLines DMS [pl_video] shortcode ( notice wmode is already set to transparent -- https://github.com/p...codes.php#L1423 )
Please let me know your feedback.
