This is all done without JavaScript and requires only two video encodes, one OGG file for FireFox 3.5, and one MP4 file for everything else (Flash / Safari / iPhone).
When looking at the video for every body's test page that can be seen here. I have noticed a green line that appears at the top of the video when viewed using google chrome. bellow is a screen shot of what i can see when i view this page. i have also tested it on a few other devices using chrome and this still appears.
