Inserting swf in an swf

i saw a tutorial on adding an swf movie clip within a running swf, i managed to add pictures and swfs within the same directory, using something like this:

var tagload:MovieClipLoader = new MovieClipLoader();

but i wanna load a flash-based tagboard into my flash file, (using service), somehow it doeswnt work when i key in

var tagload:MovieClipLoader = new MovieClipLoader();

however, when i tried loading exteral images from other websites, it loads just fine, y doesnt an swf one work?

any ideas?

o, n is there anyway to insert a html page like i would the images n flash files? meaning the entire site is under one big flash fileā€¦
