I've noticed this problem on MD Alpine as well. "Fatal error: Call to undefined function media_browser_js() drupal." This is fixed by modding ./sites/all/modules/custom/md_fullscreen_slider/inc/md_fullscreen_slider.utils.inc as follows, and you can open the enclosed screenshots fullsize for clarity:

Thanks to MeshBrains for the snippet. You can see his more detailed explanation below or the original comment here:

On a fresh install of D7, latest media module (7.x-2.0-beta1) and latest md_megamenu, got a blank screen after adding a new MDMegaMenu, saving, and then editing. Apache log revealed the following: 

PHP Fatal error:  Call to undefined function media_browser_js() in /var/www/commerce/sites/all/modules/md_megamenu/includes/md_megamenu.utils.inc on line 627, referer: http://shop.norbest.com/admin/structure/md-megamenu

Traced to a change in media module 7.x-2.0-beta1, "the media browser settings were "simplified" and moved to a library which makes the media_attach_browser_js() and media_browser_js() helper functions unnecessary, since they require more code and the loading of a file, compared to simply attaching the library."

To correct this, open includes/md_megamenu.utils.inc, line 626 and replace:

  module_load_include('inc', 'media', 'includes/media.browser');
  $javascript = media_browser_js();
  foreach ($javascript as $key => $definitions) {
    foreach ($definitions as $definition) {
      $function = 'drupal_add_' . $key;
      call_user_func_array($function, $definition);
    }
  }

with

  drupal_add_library('media', 'media_browser');
  drupal_add_library('media', 'media_browser_settings');

Hope that helps someone...
