Multiple Perspectives page movie preview in Chrome

XOT 2.1 HTML5 - using the Multiple Perspectives page (most previous issues resolved thanks Inge!) but having a preview problem when using MP4 movies in Chrome. In IE the movie preview appears in the image bar at the top, and when the movie is loaded on the panel below. In google chrome (latest version) it doesn't, the image spaces at the top of the screen are all black boxes. Anyone else having this issue? I can put an <img> into the top images bar by coding it into the title area but that shows the image again on the page below. Anyone have this issue, and found a workaround?
