VS 2012 webbrowser problem

PROBLEM 1:
I have this html file that will show a video but everytime I increase its height, nothing happens but when I increase its width, both width and height change. but what I want to achieve is only to changes its height and so I use the code below.

<style>
video {
-webkit-transform: scaley(2);
-moz-transform: scaley(2);
}
</style>

With the code above, I can stretch the video player to the size that I need but it is only stretched using the mozilla browser but on internet explorer, it is not stretched and before it can be executed, there will be popup balloon showing that it is blocked.

Going to navigate the same html file on the webbrowser, it does not show the video player on its stretched state but rather on its original size.
That is my problem.


PROBLEM 2

I have another html file, where in it has video player using OBJECT TAG. This html file executes properly on the browser but when I navigate this html file using the webbrowser control, the player is not displayed. How come? What is the problem?
