Playing M4v using the new QT Player.

Hello, I was wondering if there is a way I can have shadowbox play my M4V movies using the newer QT player and not the older one. I like the new look of the player and also the full screen option it comes with.

Here is an example of it, just click on the Demo Play button, I could not figure out how they did it: https://expressionengine.com/

Right now my movies are playing back using the old QT player.

Thank you and have a wonderful day!
