Hunted The Demon's Forge (1x DVD5) *INNO+FreeArc*

[The-revenge]

I have a question, I delete the other languages (INT,DEU,ESP,FRA) file and folder; each languages i clear 220 MB, for a total of 880 MB.
In this way, i tought initially, i can leave the original video (due to a lot of time spent to convert the video).
But the arc file is 3.70 gb !!! Why? (I obliviusly move the MOVIES folder before compress)

EDIT : I have another problem, i leave the original idea of foreing languages, and i re-encode the bik file. The conversion work, the game install correctly but i can't see the video, simply the video was skipped in a shortly black screen.
I put the folder "MOVIES" , content the re-encoded video, in the folder HTDF_DVD5 , togheter the file already exist and the the file HTDF.arc, and then I create the ISO. What is the error?
In the original install directory the folder MOVIES is in the folder DFGAME; i try to create this folder in a ISO's root, but i receive an error during installation (the folder MOVIES isn't founded)
