When I make videos from this site fullscreen, there is a large black space in the bottom third of my monitor - this worked fine a week ago, and works in IE http://www.gomtv.net/2011gstls1/vod/65716
Clicking the full screen button leaves the bottom third of the screen blank. The scroll bar is also at the top of the page instead of the bottom. This page displays correctly in Internet Explorer.

You could test turning off graphics acceleration in Firefox to see whether that fixes it.
orange Firefox button or Tools menu > Options > Advanced
On the "General" mini-tab, uncheck "Use hardware acceleration when available"
You may need to restart Firefox for this to take effect. Does it make any difference?
No, this made no difference.
