Frame Rate Issues in Browser

I was wondering if you guys could help me. I’ve just gotten finished with a nice intro movie for a web site I’ve been working on. I’ve syncronized the animations with a mp3 file. I had set the frame rate on my movie up to 30 fps so that I could have more control over the animation. Now my problem is that it seems when I load the movie on the web, it automatically drops back down to 12-15 fps (whatever default is I guess).

Is there a script I have to run to set the browser to load the movie at a certain framerate?

Any help is appreciated.
Thanks
