Android Question vitamio view

I've got an imageview in my designer script that is;

SetLeftAndRight(0%x, 70%x)
SetTopAndBottom(0%y, 100%y )


In my activity, I'm setting the vitamioview to 70%x too.

Activity.AddView(VitamioVideoView1, 0%x, 0%y, 70%x, 100%y)

But it doesn't seem to do much, I've played with values of 50%x to 70%x and the size of the video player is the same. I was hoping to cover the imageview, but it covers a bit more (of a list).

Any suggestions?
