Can a browser change the frame rate?

Greetings All.

I’m working on a flash holiday card for the college I attend. I’m experiencing problems when it’s viewed in a browser… Within the .swf, everything works fine. But once it’s embedded into an html file, it seems like the music speeds up or the animation slows down (one or the other). I was unaware the browser could manipulate.

Can anyone help me out?

Check out the card here:
