Video hotspots - Windows Media Player plug-in

Does anyone got this working?
I have been reading through group links and found a discussion below,
but none of the links works in the below discussion.

any sample is really appreciated.

I want to invoke a URL in a browser when I click on hotspot on video.

thanks
