Caching a second video for later use?

Basically, I've a 2D tiles game where the user makes several moves in a single game. I'd like to display the best (or top 3 best) moves at the end of the game. Thing is, the points awarded for a move aren't calculated before the move is executed, and right now with my current implementation, it would be a nightmare to do it.

Is there a way to save a second video w/o overwriting the first one. That would allow me to just save the highest score and overwrite it only if it makes sense.
