Freezing at Duchess Unia for some reason

[Friendo Palrissian]

I'm literally at the end, haven't had any problems whatsoever, and I get to the Duke and Duchess, kill the Duke with no problems, and when I get the Duchess to the killing minigame, it hangs up, and sometimes plays again for a second before hanging up again. I don't quite get it. Don't think it's a processor issue, but could it be the game?
