Recently I checked out few tips from some sites and tried it at home. I have airtel DTH connection. I guess it should work for other operator as well.
Use following settings.
1. Press "menu" button on your Remote.
2. Go To my settings -> system setup –> FTA Channels -> Find Channels
3. Enter following values using your remote in the FTA SETTINGS FOR SEARCH screen
Satellite: Choose any(Insat 4A ,4B or other)
Search mode: FTA+CAS
Modulation type: DVB-S2-QPSK
Polarization : VERTICAL
Symbol rate:28800( I tried this setting but its not taking hence I’ve put 28.80)
FEC: 2/3(or any)
4. Press search. It will list all the available channel, Select all.
Now you will be able to see these in your tv after 1500 Channels. User number pad to select channels after 1500.
For me couple of the channels are coming as blank but majority I’m able to see. Few of the channels which I’m seeing are Star Plus, Color Guj, Disney XD, DD National etc
