Quicktime + Frames + Firefox issue

Hey - I have a problem using a frameset (yes - i know everyone will say don’t use frames).
The problem is with playback of quicktime in a frameset and it only occurs in Firefox on both mac and pc.

The page consists of 3 frames the middle frame loads an external site which has a quicktime movie - which when visited on its own the page works fine in all browser, but when loaded into the frameset in firefox the quicktime doesn’t load. It does work properly in Safari and IE though (IE has some other formating issues but the quicktime works).

Here is the link: http://www.pushstudio.com/clients/circle2/directors/director.htm

Does anyone know what the problem might be??
thanks in advance.
