Yes, I was aware that the mod does not do anything to crush your game. I think there is only one way to disable movies, though - the one I wrote about.
Maybe you have Vista or Windows 7? These systems have various admin permissions - I recommend Googling about these. Me, I usually open IWD directory via Total Commander, sellect icewind.ini and press F4(Edit) - it cannot "not find" the file, because the file is there right in front of me. You need not create the file - you need to find it via "My computer"(for example) and double-click on it. Again, if it's admin permissions for Vista/Windows 7, you need to search for these.
