Banner calling external flv-file is way to big

I’ve got this banner that shows an external flv-file. It works just fine but it’s 44KB. And it should not be over 29KB [according to the specs provided bij the host].

Almost all of it’s weight is in the AS2 class…


import mx.video.FLVPlayback;
this.attachMovie("FLVPlayback", "my_FLVPlybk", 1, {_width:336, _height:280, x:0, y:0});
my_FLVPlybk.contentPath = "bannerVid.flv";

What can I do to keep it’s file size under 29KB? Is it even possible?
