i'm in Malta and trying to get freeview channels as in the uk, i bought freesat receiver and installed it on a dish ,,, i could get the astra 2 and when i tuned the freesat i could finally get the tv listing with the guide but the channels don't show, it says no signal but i can still see on the bar what program is on, and when i scrolled down i could see aljazeera english only any ideas?
