Your gonna have to use AH Film viewer, select the start and stop points and then save it. It will then go frame by frame where you will do your views and all. The quickest way is to get FRAPS and just use AH Film, play the film and run FRAPS (start Fraps first, then AH Film) You will record only the action, not all the AH programs... so it will be just what you see in the game withour the text buffer and such.
Any questions let me know. Batfink, Spade and Furball are pretty good at films too... I am sure they will pop in.
EDIT: Forgot to say, do this stuff first and then let me know, we will then attempt to attack the Wide World of Windows Movie Maker!
