Don't think there is any other way to solve it aside from what I already wrote about in that topic you found. If you want to make cutscenes in FPS Creator, then you'll need to set up your scene, script your events to play out one after the other, and then record the action using the player camera.
Quote: "Is it possible in FPSC to play movie and external text (as subtitle)? "
Why not just use Windows Movie Maker to add subtext to your finished cutscene once you have it recorded (not sure if it can do that or not)? Otherwise you would probably need to have the subtext display via script
during the actual recording of your cutscene; which seems like a big frustration scychronizing the text with the dialog (unless you write a script to play the next subtext in the series with a key press, then you could control it to display whenever you wanted).
Hmm. It's interesting how popular cutscenes have become all of a sudden.
