Description

Whenever I want to see a video through Windows Media Player 10 through Firefox
it tells me i do not have series 9 installed. I have WMP 10 installed, it's
newer than series 9 so this shouldn't be a problem. Even if i re-install WMP 10
it fixes nothing, it still won't let me play video through windows media player
in the browser. This is a time when I have to resort to IE so lets fix this.

Reproducible: Always

Steps to Reproduce:
1. go to a video on the internet that needs windows media player
2. have WMP 10 installed

Actual Results:  
Nothing, thats the problem.

Expected Results:  
Played the video like in IE.

- make sure you have only 1 single version of WMP installed and that it is the
latest: go to http://plugindoc.mozdev.org/windows.html#WMP to get the latest

Windows Media Player (Wiki Mozillazine knowledge base article):
http://kb.mozillazine.org/Windows_Media_Player

The web author javascript code is very long, complex, redundant, not tidy and
bloated as far as I'm concerned.

var hasVersion9 = false;
(...)
else if (window.GeckoActiveXObject)
{
//create the player
player = new GeckoActiveXObject("WMPlayer.OCX.7");
}
(...)
//check the player version
if (player != null && 
player.versionInfo != null)

Question: if new GeckoActiveXObject("WMPlayer.OCX.7") succeeds, will player have
a versionInfo member with WMP 10? If no, then the code wrongly branches.

{
minorVersion = parseInt(player.versionInfo.split(".")[1]);
majorVersion = parseInt(player.versionInfo.split(".")[0]);

if (majorVersion >= 9 && minorVersion >= 0)

What if the player has no minorVersion member?, then minorVersion will be
"undefined" and the code branching will fail.

{
hasVersion9 = true;
}
(...)


He also elsewhere relies on browser user agent string detection to determine
browser:
function isPlayer9()
{ 
  return ((this.getMajorVersion() >= 9) || 
           this.getMajorVersion() == "unknown" && 
           this.getBrowser() == "Netscape" && 
           this.isNSPluginInstalled());
}

(...)

var classid = "6BF52A52-394A-11d3-B153-00C04F79FAA6";

Rob, I checked his code for over 30 min. and he does a better job of detecting
Netscape 7 (although again with user agent string detection which is generally
bad) and WMP 10 is loading and playing the B. Larsen song with NS 7.1 and NS 7.2.

I'm getting this following error : Netscape browser does not have "Microsoft
Windwos Media Services" plug-ins installed.

What do we do ?
