Hi all, Over the past 5-6 months, I've been having intermitent probs with the Sky box, locking up, slow menus etc and now the box office movies don't work! It's been suggested to me that it's all related to the signal strength, so after having a look at the "services" option it tells me that the strength is less than half.. Is this bad? If I go up a ladder (walkie talkies/compass etc) will it make a difference? Anyone had experience in adjusting the dish? Cheers, Phil.
