ALL! Channels now have a four digit number in front and give me about 150 potential programs! It is stopping me receiving progs from the guide and it's not now possible to enter the normal 3 digit channel number. Has anyone else had this problem? It's got me baffled.

are you in non-freesat mode?

You must have added channels using manual tune and are now in non-freesat mode. Simply switch back to freesat by using menu/settings/stb mode

Many thanks to you both. Of all the things I never thought of this. Only had the Foxsat for more than two years!!
