Hi Chubbs, I'm not sure whether Virgin do individual channels they seem to prefer to do their collections although there are other means of viewing Fox, you can try here
http://livetvcafe.net/videos/25/News-Channels/most_commented/all_time/ . Also I have downloaded a programme called hotspot shield (
http://www.hotspotshield.com/en) it gives you an IP address in the states then you can go to
http://www.hulu.com/ where you can view fox and other previously aired programmes. The only live streams I've found were in the live cafe link. I know it doesn't answer your question but it may help out in the short term.
