We will now scan for SD and HD channels separately.
First we will scan for the DVB-S (SD) channels. To do this, enter the details for one transport and it will find the rest. Hit "Scan for channels" and enter the following details:

 Freq: 10714000
 Polarity: Horizontal
 Symbol rate: 22000000
 Mod Sys: DVB-S
 FEC: 5/6
 Modulation: QPSK
 Inversion: leave at auto
 Rolloff: leave at 0.35

The channel scan will take a few minutes to complete. Check the /var/log/kern.log file if you have problems.
Now we will scan for the DVB-S2 (HD) channels using the following details:

 Freq: 10847000
 Polarity: Vertical
 Symbol rate: 23000000
 Mod Sys: DVB-S2
 FEC: 8/9
 Modulation: QPSK
 Inversion: leave at auto
 Rolloff: leave at 0.35

Hopefully it will find BBC HD, BBC ONE HD, etc.
