Just got PACE Sky+ installed today by a local independant supplier and Im having problems when playing back recordings. About 3 seconds into playback, the picture freezes and the message 'No satalite signal is being received' appears. I know that the programme has been recorded because, if I set it to play at say 6 mins into the recording, it starts to play, then freezes again. This is happening to all my recordings. I will be ringing the local supplier tomorrow but, to avoid embarasment, is there anything that Im doing wrong?
