You need to go into the options section on your Sky box, scroll across to "Add Channels", then set frequency as 11.082, polarisation as H, symbol rate as 22.000, FEC as 5/6, standard as DVB-S and modulation scheme as QPSK. Now press yellow to scan for channels. Scroll down to Motors TV and press yellow again to store the channel, then press select. Now it should appear in the "Other Channels" tab on the options section.
