Any one on this board knows how to record live internet TV like for instance this site? http://www.freeetv.com/modules.php?n...ch&id=1320&d=1

I have been trying to do that by using different tools like Firefox Video downloader or a download manager but with no success so far. I can record Youtube and other videos but I cannot record live internet TV for some reason.
Any idea would be appreciated.
Thanks
