In such cases, I try to find the end of the header, usually, where the lots of zero bytes (padding) ends and the actual compressed video data starts. Cut the file there and you'll have a video with a length of zero frames. Depending on the player (media player, game etc.), it may or may not work.

One more note: there may be a disadvantage of using the same "empty" video every time when you e.g. you want to get rid of the intro video of a game. If the game starts up in resolution X and the video is in resolution Y, the player may switch the resolution from X to Y and back to X; and several times if there are several intro videos. Neither you nor your monitor will like that, so better make different "empty" videos every time you need them.
