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

auto drops? It shoudnt do that. What is your net speed connection? If your saying that the movie slows down, than it effects people with 56k for example.
