OK I finaly figured it out with Many Huge Thanks to Planck.
I figured i better post here for others .
First this thing seems to be called a INTRO
when you are in the game editor , just under the "clear" button , you will see a differant looking button , slightly ressed looking, it might say "mission" click that and set to "intro" . now from what I have experianced you have to recreate the mission because you wont be able to load or merge . place your units and triggers for camera views, or i guess if you are more advanced use scripts. but i am not there yet, so just placed triggers for the cameras. preview, make any adjustments to your movie , then save as a "user mission" . copy that mission.sqm to the folder you created in the addons for your intro . rerun OFP run your island in editor exit it, and your INtro should be working .
Thanks again to all the Help here at OFPEC and other OFP sites all over the net . and to BIS for the greatest game on the planet .
PS I toke the easy route and just left my Player unit as a Humvee with no waypoints.
