Embedded Video within scrollable DIV/ Browser Scrolling issue

I have a Scrollable DIV that contains an embedded youtube video and some text beneath. The (mac) browsers Safari, OmniWeb, Opera, IE (Firefox being an exception) seem to display the video outside the boundaries of the DIV that it is contained within - regardless. That is, the video ignores the DIV clipping.

Here is a link to demonstrate http://mcdxliv.cabspace.com/sample.html

Furthermore upon scrolling the content, a ghost image of the Video (that is outside the DIV clipping) remains. Scrolling up and down results in more of the same effect…

Any ideas? Also is this happening for PC users too?
