Loadclip won't centre on screen

hi all i have a movie clip symbol on my stage, called ‘symbol’, i have centred it on the stage using the following…

symbol._x = Math.round(Stage.width / 2);
symbol._y = Math.round(Stage.height / 2);

works fine, however inside the ‘symbol’ mc i have this on my timeline

_root.symbol.loadclip = "home.swf";

there is a transition and then I have this

getURL(loadclip, "_level7");

home.swf loads but doesn’t load centred, it just loads on top of ‘symbol’, and the top left hand corner about 5 pixels down and to the right any ideas? i’m struggling… :frowning:
