Thanks. Quite a good solution that is in terms of finding a work around with the present restrictions.
But I am not quite pleased with it though. As in, its not elegant solution. I don't want to change fps of any of the movieclip as then they will not animate the same way they should. e.g. background effects will become slower/faster.
I am looking for a solution where the main movieclip doesn't change fps but a child movieclip/window or something else will have a different fps that would be same as exported swf.
If an html page can show swf of multiple fps in one window itself, why can't flash itself?
Is it possible to do by playing with html with dynamic text?
