If you want channel 5 on sky try Services-> System Setup-> Add Channels.
When there put in:
Frequency: 10.773, Polarisation: H, Symbol Rate: 22.0, F.E.C.: 5/6 and go down to Find Channels and press Select.
When there, add FIVE by clicking yellow when it is highlighted. And press Select when done.
After that you will find it in Services->Other channels.
Bit of a pain and you cant sky+ it.
