Hello! I have read few post about this problems but I could say I have different problems in different browsers :(

the video link is this: (mp4 video)

and the problems are:

In Mozilla-> Cant play until it totally loads. Full screen perfect
In Chrome-> Fullscreen doesnt really work. I dont know really where it put the full screen video.
In IE-> Fullscreen is half working, all the content of the webpage can be seen anyway scrolling

Thanks for your help!
