video on dual montiros

We are currently installing video survaliance cameras in our office.  We can access the video from one monitor, but when we move IE to the second monitor the video goes away.  I have noticted that happens also on Windows Media Player.

Any suggestions?

Who is Participating?
Most video players only work on the display designated as primary with WinXP.  Win7 allows multiple monitors to be used, I believe.

I would suggest that you move your window that displays to the secondary display before you start playing the video.

You can also try moving media player to the secondary display and then pressing 'stop' and 'start' on the player.
How is your second monitor connected?  Do you have enough video memory on the secondary video source to support your configuration?

XP does not have this problem, in my experience.  Our systems with dual-head Matrox adapters can be run in separate dual-monitor mode or in "extend desktop to second display" mode.  We normally run them in "extend desktop to second display" mode, set the "open tasks on monitor 1" option and drag the display tasks over to the second monitor once they're open.
If the application uses a video overlay, it will exhibit this problem.  For example, in the Secondary display section refers to this problem.  The Matrox Parhelia cards were an exception to this problem.
