Need to display full screen interactive video when clicked on maximize button in the slide

I have used interactive video in the half of the slide. There is no skin for interactive video so i have used customized maximize button, when i click on that i have to open video in full screen. I have added media video in the popup but problem is when i click on maximize button popup video starts playing from the beginning, not from where the video is playing in small screen. Can somebody help me on this?
