Is chipping a box basically cutting talkback?
My uncle has got a ntl box but he sais its not 'chipped', do i need to just cut talkback?
And how will I find out the BK and IRD, doI need a cable?
What you do need to do is read and search as these are basic ( very basic) questions that have been answered on many occaisions.
