Twice this week I've set the box to record from BBC HD, (Messiah and Torchwood) only to notice that it doesn't start recording. Then when I've switched to the channel I've had the "no satellite signal is being received" message. Both times, I quickly switched to normal BBC1and 2 to record the programmes. Whilst they were recording though, I then got the same "no signal" message on every other satellite channel. BBC1 and 2 were viewable and recording fine, but no other channels were available until the recording stopped. What's all that about??
