Double Video playback of WMVs

Playing a video is IE6 results in a double playback of the video. It hard to tell what is going on however it appears that there are two videos which may be stacked on top of each other. The front video loads first and is displayed in the video player. A second video loads a few seconds later and is playing underneath the first video. This creates the effect of a dialog echo which is rather annoying. The first video can be controlled by the video player buttons and therefore can be paused however if paused the second video continues to play revealed by the audio. If you resize the browser window and move it about your screen you can sometimes see the second video playing.

I have test site up and running is you would like to see the problem: http://www.fresh.fishfever.com

This problem isn't apparent in Firefox 2.0.

Any suggestions to correct would be greatly appreciated!
