So I noticed you faggots and mouth-breathers looking for this demo hud which allows you to rewind, fast forward, pause, etc etc... while watching .rec files. Surprise surprise, all it took was one whole google search of "cowboy demo hud tribes" and it was the first fucking result. I've tried it out (used it on my "fun times in BR" video... LOL!) and it works pretty well.
