Use Embedded Flash Vid As A Link - FLASHVARS Or JS?

Industry feedback in 'advertising world' is that I really could do with moving mini flash vids as thumbnail links, not static thumbnails if possible. This is where I am up to for you kind folk to see - [URL] The playback of the flash vids (in the big playback area right/mid of screen) from the JPG thumbnail links on the TOP ROW works FINE, but how do I similarly call that 'BIGFLASH' function to display the video right-centre linking from the JW Flash Player vid thumbnail equivalents on rows TWO and THREE?

Do Flash vids defo overide all other functionality (and thus the 'linking hand' hovering icon) we could otherwise use to "couch" the object (ie, in this case, the calling of the flash routine) like using javascript OnClick, etc or do we need to try and "con" the FLASHVARS within the flash player using the flashvar "DISPLAYCLICK:" ( http://developer.longtailvideo.com/trac/wiki/FlashVars ) to do something javascripty and invoke the 'BIGFLASH' function? The parameter options seem limited though don't they... as far as I can tell you can't use the DISPLAYCLICK flashvar to call a bespoke JS routine. I wonder if it is possible to put a transparent layer OVER the flash vid in JW Player and use that as the link, or does flash not allow other layers superimposed over it?

My hands seem to be bound unless I am not seeing the wood for the trees! I really like the layout as it is and the coding and the fact I'm nearly there so I would hate to have to do something radically different at this stage. Why is such an obvious function so difficult to achieve?!
