If you already have the video, then all you need to do is to change the player.inc file to use HTML5 video playback as opposed to flash. Unfortunately, this forum isn't going to be the resource for what you need to do to make HTML5 work as vShare doesn't use HTML5 (it uses Flash). There are several Youtube videos out there on how to use HTML5 video. All you would need to do is grab their example codes and plug it into your player.inc file.
