Controlling MedeaWiz Sprite with Arduino

I have looked through the Sprite instruction manual, and it just is not clear to me how I interface the arduino with the player to control videos. My project is this: a static video, four RFID sensors that when triggered play a different video (and then back to the static video), and then a final video when all four rfid are placed properly. I know it is possible through code because I have done something similar with just audio, but I want to up the project to video. It is possible to interface the arduino with the player, but i cannot find any clear tutorials or instructions. Any help would be much appreciated.

It seems you forgot to add a link to this mysterious sprite thing.

Video and Arduinos are not good friends, so no idea where an Arduino could possibly come into play.
