tuner a needs to be of if you not using a sat dish on it, then tuner b and c need the same settings in both of them
You don't have to disable anything if you're using sat and cable.
How is the hdd going?
@Mr. Jailer Any luck with this yet?
It's a 32GB hard drive. I had already followed your setup instructions, it appeared to have formatted OK, but said that a partition or something was in use. Perhaps that's why it isn't working. If I connect the HDD to laptop, is there a 3rd party software I can format to the desired format?
Disconnect the HDD and leave it disconnected, restart the box.
Go to Plugins > USB Format and follow the instruction, then restart the box.
Then go to Mount Manager and set it as /media/hdd if it isn't already.
If your not using a terrestrial aerial the slider needs to be off.
The other thing sounds like the power switch. Does the box go off if you press it?
Check in autobouquetsmaker that the section you want isn't hidden.
