I dont have it installed right now, but are there any mpq files in the dir? If so, look in like /movies or /intro something like that and rename their dir to *moviename*.mpq.backup and then make a text file in that dir and use the same file name *moviename*.mpq and it should skip it.
This worked on another game that I dont remember the name for, if not I will install it and see if I cant do anything about making something to skip the intro.

Maybe tonight we'll fly so far away... We'll be lost before the dawn...
