Re: Curious about replays
There are many programs availiable (I think for free), which take a video of your screen. So if you play the replay with that in the background that should work.
Re: Curious about replays
replay files save army composition and player commands (what mouseclicks where issued when). It's a "replay" in every meaning of the word. So there is no way to "convert" it into a movie file (that is built from sequentive images). But like Myrddraal said there are tools that can record what happens on the screen and save it into an avi/movie format file (FRAPS for example).

Thanks a bunch guys. I may know next to nothing about modding, but at least I can do something now. ~D
