0. If you want to save additional ~5GB space, run "Remove_Audio_from_Videos.bat" before you compress the game.
It is highly recommended to make backups of videos if you are being asked. Just choose [Yes]. I just tested 2 videos ingame and my choosen language is present, so I think all other videos should be fine too.
1. Run _DiskSpan.bat, choose option [21] and type in
Code:
xoodle+srep+*
* = LZMA, LZMA-MT, lolz{:options}, ...
Note 1: Backups of movie files can be found in [GameDirectoy]\_Backup\Movies
Note 2: I don't have tested compression and installation yet.
Edit: If you get error on xoodle on nearly 10% use the FIX attachment.
