Where did i go wrong?

I redid this flash animation I made of a car wheeling by,

you can check it out at www.team-xdi.com/main.html

But the swf loads differently than it plays when i preview it in Flash MX. Why is this happening. I checked the fla to see what is wrong but I can’t seem to figure it out.

Why does that car stop for no reason then all of a sudden after like 1min , another animation sequence starts and then it loads the buttons. ? What am I doing wrong here?

I have 2 scenes In this fla. 1 the first part you see, 2 the part when you click on news.
