If you could help that would be great !

Answer 1

What you're looking at is obfuscated code. You can try figuring out what parameters are being passed into it (maybe by using Firebug and that Javascript debugger) and then get the return value out of it. But obfuscated code is called obfuscated for a reason :).

Answer 2

It has been compressed using packer. This page explains how to unpack it.

Answer 3

According to jsbeautifier.org this unpacks to:

document.write('<object id="ie_vid"classid="clsid:67DABFBF-D0AB-41fa-9C46-CC0F21721616"width="640"height="318"codebase="http://go.divx.com/plugin/DivXBrowserPlugin.cab"&gt;&lt;param name="custommode"value="Stage6"/><param name="wmode"value="transparent"/><param name="previewImage"value="http://i/00009/212fw9jbfz7i.jpg"/&gt;&lt;param name="allowContextMenu"value="false"><param name="bannerEnabled"value="false"/><param name="previewMessage"value="Play"/><param name="autoPlay"value="false"/><param name="src"value="http://66.90.73.51:182/d/zvq6lstdylqvn6lrwin6bli5reamli6ry5ewvwlk5mpa/qdnonvmiasgyh.avi"/&gt;&lt;embed id="np_vid"type="video/divx"src="http://66.90.73.51:182/d/zvq6lstdylqvn6lrwin6bli5reamli6ry5ewvwlk5mpa/qdnonvmiasgyh.avi"custommode="Stage6"wmode="transparent"width="640"height="318"previewImage="http://i/00009/212fw9jbfz7i.jpg"autoPlay="false"bannerEnabled="false"previewImage=""allowContextMenu="false"previewMessage="Play"pluginspage="http://go.divx.com/plugin/download/"&gt;&lt;/embed&gt;&lt;/object&gt;')
