: Here's a tutorial: 1. Place the movie in the game folder and name it
: "Movie".
: There's no step 2 :P
: I don't know if there are any requirements for the contents or format of the
: movie itself.
IIRC, Marathon will only play it at 320x240 resolution, centered, and scaled up. So if you have a 640x480 movie file, the middle 320x240 of it will be played (scaled up to full-screen, or at least full-area-Marathon-is-displaying-to). It might be justified to some corner instead of centered, I don't recall.
