FLV and exe files going black

I can get the FLV files to play as long as I don't tell the projector files to play full screen. If I do, as soon as it hits the first FLV file the projector file goes black and when I hit escape the file has quit running. The script that I have tried for full screen is as follows...
flash.system.fscommand("fullscreen", "true")
and
fscommand("fullscreen", "true")

The script I have for my two instances of FLV files (i resized them) is as follows:
import fl.video.*;

// Video component instance name
var flvControl = display;
var flvSource = "rel-wdb019sr-022_x.flv";
var flvControl2 = display2;
var flvSource2 = "Wedding2.flv";
// Loop the video when it completes
function completeHandler(event:VideoEvent):void
{
flvControl.seek(0);
flvControl.play()
flvControl2.seek(0);
flvControl2.play()
}
flvControl.addEventListener(VideoEvent.COMPLETE, completeHandler);
flvControl2.addEventListener(VideoEvent.COMPLETE, completeHandler);

// Set video
flvControl.source = flvSource;
flvControl2.source = flvSource2;

Does anybody have any advice?
