I noticed that channel 4 HD channel has dissapeared, done some googling and it appears it has changed frequency.

Looking on kingofsats the channel info is:
Astra 1N 11127.00 V 44 UK DVB-S QPSK 22000 5/6

Now ive changed this in silverfox's channel list but still get a service unavailable message.

Anyone got any ideas or correct settings please.
