Problem Loading .flv video from Server

On http://www.fuchsia.biz/video.html there should be a flv file loading in streaming. It works perfectly when tested locally…but simply it doesn’t start What am I doing wrong? I read somewhere http://kb2.adobe.com/cps/194/tn_19439.html that Windows Server 2003 doesn’t support flv streaming. The article proposes a solution but I simply have no idea how to carry out the following adaptation:

On the Windows 2003 server, open the Internet Information Services Manager.
Expand the Local Computer Server.
Right-click the local computer server and select Properties.
Select the MIME Types tab.
Click New and enter the following information:
Associated Extension box: .FLV
MIME Type box:flv-application/octet-stream
Click OK.
Restart the World Wide Web Publishing service.

If there’s an easy way out please help!!!

Thanks Thanks Thanks
