I'm using SU 4.9.0. With the YouTube Advanced shortcode, there is one option that we really need for it to display correctly. You can add a wmode=transparent option to a Youtube embed URL to fix a problem with z-indexes in IE (e.g., see http://stackoverflow.com/questions/9074365/youtube-video-embedded-via-iframe-ignoring-z-index for a description of the issue) . Without this option, the YouTube player's iframe appears above all other page content, including, for us, drop-down menus that should be above it. If I manually add the embed code with the wmode option (not using SU), the submenus appear correctly, but we lose the responsiveness and other features from SU. Our site is in development on an intranet, so I can't give a link for it. I can send you a screenshot of the issue if that would help.
If there is a way to add this option to the SU shortcode, that would be great. Thanks so much for your time! We love your plugin!
