How can you test your movie for download time?
I belive for that to work, you preview the movie in Flash itself.
Choose Control > Test Movie.
Then press Enter to stop the movie being played.
If necessary select a new modem setting from the Control menu.
Select Control > Rewind to make sure you are at the beginning of the movie.
The last step: Choose View > Bandwith Profiler or use the keyboard shortcut Ctrl + B
I hope that helped. If you have any further questions or comments, please don’t hesitate to reply back.
