How do I Record video of the game and use it as replay

ENG: Hi, I'm doing a soccer game and I need to go periodically saving video so that every time a player hits a goal to show a replay

ESP: Hola estoy haciendo un juego de fútbol y necesito ir periódicamente guardando video para que cada vez que un player mete un gol mostrar un replay

I've seen it done with save/load state. I don't have the time to make a capx now, but I'll try during lunchtime in a few hours... Stay tuned!

Thanks for the information if you do a capx example would be great.
