Flv and mcLoader Class

Hi,
Does somebody knows what is happening?

I'm using the mcLoader class to load all my external swf files, everything worket perfectly until I decided to use flvPlayBack on one of those external files. If the player is on my main stage it works great and if I run directly the loaded swf it also works, but now when i run the external swf through the mcLoader the player doesn't appears.

my mcLoader code:


var mcLoader01:MovieClipLoader = new MovieClipLoader();
mcLoader01.loadClip("clientes/targetTrade.swf",mcConatiner);



The flvPlayer should be on the second frame of this targetTrade.swf ("click to watch the video")

thanks,
Peter
