Here are some free services I found to check live TV coverage of football matches. You can also find satellite details of the channels at some of the sites. If you have a dish and able to get signal from the satellite (if it is a fta-free to air) you can watch at these channels.
http://www.liveonsat.com (one of my favorite)
http://www.footballonsat.com (some times they give live links,also satellite details)
http://www.telefootball.com (gives satellite details too)
http://www.livefootball-tv.com (also gives satellite details)
http://www.footballtv4free.com (channel list)
http://www.goalzz.com/main.aspx?region=-2 (not perfect but good for Asian matches)
Some times you really need to check all of them because schedule can change during the day.

I hope it will help some of you
