Using Javascript to stop an FLV?

community... i need your help.

I have a webpage that has a flash movie playing (swf that plays an FLV)... and when the user clicks a link on that webpage, it opens a pop up window (SOLIDBOX, similar to floatbox) with another flash video playing... but unfortunately the initial movie is still playing! so they are both playing...

is there a way to use Javascript so that when the link on the webpage is clicked, it STOPS the first video, and opens the pop up with the second video at the same time?

you can see the annoying results of BOTH playing at the same time here:

(click on the yellow starburst (DEMO VIDEO GREETING) to open the second video window)...

any help would be very much appreciated! :confused:

Thx,
DJ
