i found this on GameGuru & it's called
Game Cam. it allows u to record your game sessions in real-time, complete with sound.
i'm not sure if it works with <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> or not. feel free to try it out.
by the way, it's designed to work with directx 7, 8, 9 & opengl games.
