Stp flv playback from loading

Hello,
my home page contains a scroll panel whose thumbnails open different swfs on the main page. These swfs sometimes contain flvplayers. Within the swfs, i can navigate to a different frame that has no flv player and close the streaming by using the following code:
myFLVPlayback.getVideoPlayer(0).close()

However, from the home page, when i click from thumbnail to thumbnail, the swfs load but the flvplayers seems to continue streaming in the background, eventually, after many clicks the loading is very slow and i can hear the overlayed sound. I need to tell flash to close the stream on thumbnail click, but since the stream is from an external swf, how can i address it within this page?
thanks
