Flash SWF/HTML animation preview stops at the same time (around 9 minute mark) without reason. (CS5)

Question

I have a good sized animation that I am attempting to publish using CS5, but for some reason the animation always stops around the 9 minute mark.
I don't have any actionscript telling the animation to stop at that particular point, and regardless of how I order my scenes, it always stops at the same time.
Here is the only actionscript I have, and it's in the first scene:
movieClip_1.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextScene);
function fl_ClickToGoToNextScene(event:MouseEvent):void
    MovieClip(this.root).nextScene();
My theory is that the animation is too big somehow, and Flash can only load up to a certain point.
I haven't been able to find any documentation on such an issue so any help is greatly appreciated.
Also, I'm using a TLF text, but it loads and displays properly in the animation.
Cheers.

Thanks for the response!
There are 17483 in the main timeline across 9 scenes.
I tracked down where the animation stops and it does seem the limit is 16000 regardless of ordering.
What I tried to do was boil each scene down to a movie clip and play each one in the main timeline in one frame each.
I have an actions layer in the main timeline with a stop(); in each frame for a movieclip.
Then I have an actions layer in each movie clip with a MovieClip(parent).nextFrame(); and a MovieClip(parent).gotoAndStop(1); in the last one.
For some reason that's not working though, it just loops through the first frame of each movieclip without playing any of them?
Could you tell me how I could work around this limit/If I am approaching it the right way?
