What is the maximum height of the dynamically generated movie clip can be?

I am trying to test it. I am loading swf’s into movie clip with XML stacking each other vertically. I found out that after movie clip is reached the height of 65000 px the other loaded swfs will not be loaded correctly. They are loaded from the 0 point again overlap previously loaded swfs. I am wondering if there is a fix for it or it is beyond what flash can handle. Thank you.
