1. Create a folder named „flash“ at your public Dropbox folder.
2. Upload all files and folders from this zip file to the prepared Dropbox folder.
3. Convert your desired video file to the flv format and name it „yourvideo.flv“.
4. Copy the converted file to this subfolder: /dropboxusercontent/public/flash/videos
5. Get public Dropbox links for all files that appear in this html script.
These are: http:// …
dl.dropboxusercontent.com/xxx/flash/swfobject/swfobject.js
dl.dropboxusercontent.com/xxx/flash/swfobject/swfmacmousewheel.js
dl.dropboxusercontent.com/xxx/flash/settings.xml
dl.dropboxusercontent.com/xxx/flash/videoPlayer.swf dl.dropboxusercontent.com/xxx/flash/swfobject/expressInstall.swf
[xxx is a placeholder for your link specifics]
… and here you can see that it works …
[As of March 2017 Dropbox has disabled public folder sharing, so this does not work anymore, at least with Dropbox.]
