WMP on modalpopup does not stop on IE

Hi i am currently having troubles with my embedded Windows Media Player in my modalpopup control.

When i close my modal pop up on IE, the video carries on playing.

On the other hand, i tried in chrome, it stops when i close the modalpop up control.

I have seen many suggestions about the WMPlib but i couldn't find WMPlib control as i am using ASPNETVideo.Net3.dll and not WMPLib.dll/

Any help on this?

Many Thanks
