Hey, took me a while to find out how to get rid of the annoying splash screen and intro movies; if this information isn't on the site (I might have missed it) it might be worth sticking or adding to the FAQ since the thread I found it on was kinda buried and gives no instructions.
The file I used was originally from SimCutie (didn't edit his\her file so all credit to them).

How to make work?
Open up Skip-Civ4-Intro.zip, there should be 1 file called CvIntroMovieScreen.py, we are going to place this file into the Python\Screens folder of BTS, for me this is:
C:\Games\Sid Meier's Civilization 4 Complete\Beyond the Sword\Assets\Python\Screens
make a copy of the original and replace it with the new file and you are done
This works with all versions of Civ IV as far as I can tell, just place it in the appropriate folder since each version (Vanilla, Warlord, Beyond the Sword) have their own Python folder.
I'm not sure what SimCutie used to make the file, I tried making a blank text document and just changing the name & file extension but that did not work, so I am guessing he\she knows whatever Python is and made a proper replacement. I re-uploaded the file on this thread but you can get it from SimCutie's original post (the link is at the top of this post).
EDIT\
Actually I just checked and SimCutie did give instructions (sorry, I read about 10 different threads), here they are.
Maybe place their post somewhere in the FAQ?

So, I come up with this. As added benefit, it will remove intermediate picture shown for 2-3 secs between 2K games movie and Civ4 intro movie.
Just put CvIntroMovieScreen.py file in your My Documents/My Games/Sid Meier's Civilization 4/CustomAssets/python/screens folder.
