Detecting download speed

I have an animation I really love up on my site, but it is too big for modem users. I need to add either an automatic (preferred) or a manual choice for low or high bandwidth users.

I’ve seen references in the flash 8 professional help files to a “Bandwidth Selection Template” but cannot seem to find it anywhere.

I’m pretty much a noob, so I don’t know much actionscript. If anyone knows of a tutorial or pre-made solution for this I would REALLY appreciate knowing about it…

thanks!
