baffled by loss of stations

[santaanita]

hi i hope someone can help me out a i am baffled by loss of stations on asta.
i live in central portugal,but did not suffer from loss of stations when astra 2e and 2f came on line ihave a 1.8 mtr dish,2 weeks ago we went away for a short break when we returned we can only get channel 4 and channel 4plus 1 on the new sat.all the old ones sky news pick cbs are unaffected.
no itv bbc etc,the picture on channel is excellent no loss of strengh at all.
now the puzzle for me is that the channel 4s are the irish ones and this is on my old sky box,
i have tried two other freesat boxes one is a telves and a grundig and put in the transponder coes for channel 4 nort ireland but niether box can find them.only the old sky box.
any ideas
thanks in advance

Hi,
The irish versions of Channel Four are encrypted, and on a difference beam (European beam) to the free to air versions (uk beam).
And so the irish versions will have better reception where you are, than the free to air ones.

And the reason why your "free to air" televise and Freesat grundig will not pick the Irish c4s up is that they are encrypted....so will not show on a "free to air" box.
