hya ive got a 1010 phase b on tw ive done the talkback mod by cutting the small track in the tuner can, the middle light flashes all the time now, but i can still get interactive on the bbc channels by pressing the red button, and i get the pin option on sky mov 9 and 10 but none of the teleport functions work, ime a bit worried as on my other box which is a 4000 the red button doesnt work at all ? is this normal for a phase b ? in diagnostics it says return path is off.
