Scene load before video (Handled Android)

Hi, I search a solution to my since 3 hours now so if someone can help me to know why this doesn't work that can really help me :).

if someone got an idea : http://pastebin.com/hwddtCwQ (I know it's little bit creepy cause testing since 3 hours :/ )

The result of this is Unity (or Android devices) can load the next scene before reading my video. It's like he can show me 1 or 2 frame before start the Handled.PlayFullScreenMovie( blabla ).

Thanks in advance for the help :'(
