There is an error in hexbox application that you can download from "http://www.hexagora.com/hexbox/download.htm" as hexbox.zip. The file OSplayer.swf is called as OSPlayer.swf in code. This little difference supress the automatic playing of movies if you are using a Linux server!
And by using this extension for video (.flv files, for example), can the user completely hide the controls and even the video borders/frame, besides making it start playback automatically? As to video frame/boarders, is it possible to make video windows appear just like with videolighbox.com ?
