Preloader Help Needed Please and Thanks

Ok, well i have been using the old way to do preloaders for quite some time, and I thought I would try and keep up to date, and figure out how to use my old preloader but so that it doesn’t stutter before the movie is played, what I mean here is that the loader when it finally comes into view is already at say 44% when you actually get to see it etc. What am I doing wrong? I’ve seen people with animated loaders and others that have a ton of stuff displayed while their loader is loading the rest of the content…could someone clue me in or show me a better tutorial on how to improve my loaders? Thanks in advance.

Oh, here is the code I’m using on the first frame of my movie for the loader:

bytes_loaded = Math.round(_root.getBytesLoaded());
bytes_total = Math.round(_root.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
_root.loadBar._width = getPercent*140;
_root.loadText = Math.round(getPercent*100)+"%";
if (bytes_loaded == bytes_total) {
