Without seeing the code for the preloader, it's hard to know how they're calculating the download.

The most reliable method I've found is like this:

loadedPercentage = Math.ceil(100 * this.getBytesLoaded()/this.getBytesTotal());

Re: scenes - once exported, Flash is just one long scene rather than the separate ones you see when editing (which is why you should make your frame labels unique)

Cheers,
Nigel
