Loving MD Slider. It's an excellent module.

One request is that the size of the video in the lightbox be configurable in the MD Slider options.

I managed to increase the size of the box by editing md_slider/js/mdvideobox.js from line 54 to 59.

var options = $.extend({
initialWidth: 960,
initialHeight: 590,
contentsWidth: 960,
contentsHeight: 540,
defaultOverLayFade: 0.8,

Hope this helps someone out.
