R – Cut Sound of an Embedded Video

Well, if you can just remove the swf after the click, like this:

var request:URLRequest = new URLRequest("external.swf");
var loader:Loader = new Loader(); 
loader.load(request); videoContainer_mc.addChild(loader);

skipIntro_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownSkip);
function mouseDownSkip(event:MouseEvent):void { 
    videoContainer_mc.removeChild(loader);
    loader.unloadAndStop(true);
    gotoAndPlay("ending");
}

If you can't just remove the swf, then you'll need to stop the movieclip that contains the video inside the loaded swf.

Flash "always" uses the html's path as the base for relative paths (more specificaly, all URLRequests)... This is unless the base html parameter is set (see here).

However, I remember that when FileReference came out in AS2 (dunno about NetStream), for some reason its paths were always relative to the swf... when AS3 came out I think URLRequest fixed it.

I don't know which "VideoPlayer" class you refer to... a quick google search gives me a link to an AS2 class, so if you are using AS2 (bad tags BTW ^^) you might be running into the problem I mention.

And now that I think about it, NetStream doesn't use URLRequests (is it the only external loading process that doesnt?), so it might be related to that... maybe URLRequest.url gives a corrected url, I haven't tried it.
