[CS3/AS2] Loader code: Can I load a portion of the swf instead of BytesTotal?

I’ve gone through the two loader tuts on this site (http://www.kirupa.com/developer/mx/preloader.htm & http://www.kirupa.com/developer/mx/percentagepreloader.htm) and they are great. But they both use the ‘getBytesTotal’ function.

Is it possible to tell the loader to only load a portion of the swf, like 50% of total bytes - or upto scene 5?
I’ve got a 5 min long interactive ‘demo’ and I don’t want the viewer to have to sit and watch the loader while it loads all 5 min of content.

Thanks for your help!
