Windows Media Player - Is It Still Possible To Do This?

I remember a year or two ago we did some movie encoding and about half way through the clip we coded a console in to it so that when it hit a specific part of the clip, it opened a new window.

I know there were some problems continuing this method of getting traffic from the filesharing networks when Windows upgraded Media Player but i was wondering if anyone had tried this method again since there have been a few updates?

Does anyone know if it is still possible to encode consoles in to movie files so they open when played with Media Player?

Regards,

Haven't seen it for a long time, probably the player stops it now.
Really, really annoying form of popups - Angst provoking almost !
- Zone Alarm-banned Media Player from the web for that reason.
