they are probably getting the matches from another provider from a different satellite...
there are many other satellites in the sky, and not just sky uk that do pay tv football....
if it was itallian it could have been from sky italia - on hotbird at 13 degrees - for which you will need to subscirbe to them using a sky italia card and sky italia receiver...you cannot use a sky uk receiver to watch sky italia (before you ask!)
this link shows which satellite channels do scottish footie matches....
*** L.J.s LIVE Sport on Satellite TV. Live Soccer on TV. Live Football on Saetllite TV.
but the link suggests its either hungarian or polish (Polsat)...unless they are getting a feed from somewhere else, like subscibing to an internet feed (via a proxy or similar) from the clubs site...
