Hi Martin,
The video with that shortcode works perfectly too.

The video checkr says “Admin video: Ok”.

But now i think where is the problem from. We are using a theme called WPLMS that let us to upload courses. This videos are in every unit, that pass in the same page with Ajax. Is possible that through every unit change it lost some of the preloaded resources? The player says “Im sorry, but the player looks broken”, and did a check template and it throw this:

jQuery library http://cursostecnicos.com/wp-content/plugins/LayerSlider/static/js/layerslider.kreaturamedia.jquery.js?ver=5.3.2 found, but unable to check version, please make sure it’s at least 1.7.1.

It appears there are multiple jQuery libraries on your site, your videos might not be playing or may play with defects, please check.
Template checker has changed. Just open any of your videos on your site and see if you get a red warning message about JavaScript not working.
FV Flowplayer script found: http://cursostecnicos.com/wp-content/plugins/fv-wordpress-flowplayer/flowplayer/fv-flowplayer.min.js?ver=6.0.3.6!
jQuery library 1.7.1+ found: http://cursostecnicos.com/wp-includes/js/jquery/jquery.js?ver=1.11.3!

The video in the post works perfectly even whitout the shortcode you shared me before (also in my Windows Phone).

Any ideas?
Thanks,
Carlos
