Rapture was never good when it was on before. All I can ever remember is crap music and people falling off BMXs, but each to their own
Anyway, is NTL cable full? Yes and no. I think they're in a position whereby it would be too much of a squeeze to add a new channel to the current multiplex structure (it would impact too much on existing channels). I don't know how much space there is left for new muxes; it's entirely possible there isn't any. So they'd have to turn off an analogue channel first, which would actually free up enough space for 10 or so digital channels...
So is it full? It depends on your definition!
