If you change the _x and _y values immediately after calling loadMovie or loadMovieNum, it won't work, because when the movie loads, it will obliterate the values you set. You can work around this by using an additional container movie, and changing the _x, _y values of the container (which won't get obliterated).

e.g.

code:


_root.createEmptyMovieClip("cont_mc", 1);

cont_mc.loadmc = loadMovie("xxx.swf");

cont_mc.loadmc._x = 100; // this won't work

cont_mc._x = 100; // but this will

cont_mc._y = 200;
