For others like me interested in changing a bit the original game missions I've found another way of making things work .

Taking the "Scorching Sands" mission as a example:
Go to the Editor and load the "2-crusader" "0.mi" file and save (so it show up in the game folder "Men of War\resource\map\single\2\2-crusader\").
Press F2 and save the map as a new one (example "scorchingsands").
Exit and copy the "0.mi" inside the "2-crusader" folder to the "scorchingsands" folder.
Use winrar to open the "game.pak" file in "Men of War" folder, locate the "2-crusader" folder and copy to the "scorchingsands" folder the remaining files that GEM Editor hasn't created.
Go to the editor and make the changes you want in "scorchingsands" mission.
If you don't know yet, read the sticky of the GEm Editor sub-forum to make a mod, but instead of using "0-3-training" for the mission use the real name ( "Mods/mymod/resource/map/single/2/2-crusader" ).
Copy to that folder all files from "scorchingsands" folder.
Launch the game, activate the mod, and the mission intros, voices and movies should work like the original, after the end of the mission it even goes to the next one.
