I don't understand the question. All 8 episodes in season 1 of Life on Mars have been shown on BBC1.
Dalziel and Pascoe has been on for a couple of weeks (although it is taking a break while the Commonwealth Games are on).
Just thought, are you referring to the repeats with signing? The next one is on 28th March.
BBC4 will soon be showing repeats. (2nd April onwards).
