I just downloaded about a dozen excellent campaigns for my own enjoyment when I decided to see what the authors had done with their video tracks.

There is a huge divergence in what I have been so kindly been instructed to do and what all of these very playable and video filled campaigns contain.

There is no changing the all.ini or all.properties or anything like that. All of the tracks have the extension .ntrk included.

They all work very well and all they have done is to put a line in their campaign configuration referring to their xxxx.ntrk track and it's companion xxxx.msg file.

I am missing something very obvious and need help from someone who has actually placed a video track in a campaign using Vista. Can anyone assist me?

Try asking in the mission builder forum.

This forum's about making standalone movies to watch outside the game, not campaign movies.
