I have a Flash movie that I'd like to feature on my site. The video dimensions are 640x480, but I'd like to show it at 320x240. I know I can specify width and height in the embed/object parameter, but then the browser still downloads the whole file. which is quite hefty at 9.3MB. How would I rescale the movie so that (hopefully) the download/stream size is much smaller? I'm on a Linux box.
