published project doesn't work correctly

Hi,

I made a small project to test articulate. I  published it for web, with the option html5 and iPad on and uploaded it to my site.

If I check it on the computer it works ok but, if I open it with chrome on my samsung tab the video in my project doesn't start. (black screen)

With the standard browser from android it works but the project is larger than the screen..

Can someone explain me what I did wrong?
