Sorry to poke my nose in here, but I live in south Manchester (Gatley, to be precise) and, although we have no problems picking up transmissions from Winter Hill and receive very good pictures and sound on all channels, we have been having intermittent loss of EPG signals.
Probably quite unrelated to the OP's problems, but just thought I'd mention it.
