Northern Ireland Channels are not working SKYBOX V8s!

[sparvez14774]

Hello,
Just wondering if anybody could help! I brought over my SKYBOX V8s when I came to Northern Ireland. I plugged it in to the existing SKY Dish already in the house but most of the channels are saying "No Signal" a part from Sky Sports & Movies are working fine and I've the latest Sky Numbered Channel List updates as well from CWAITE.
Just wondering if there are any other setting I needed to change in the box!
Would much appreciate if you could help.
Many Thanks in advance

Should work all of the UK and Northern/Southern Ireland all use the same satellites and frequency's with no change

Has that dish previously worked OK with other boxes?
