Well, I think that you have to know your equipment better, and there is no need for me to look google, I am not encyclopedia. There is enough for me what i have (DM800HD). We are not technical support forum, we are sharing forum. We provide you just with settings. And this is YOU who must find out all technical details for your receiver, consult technical support of your receiver, etc etc.
If you don't know how to modify mg_cfg file and your receiver is manufactured with the ready built-in emulator etc., you need to visit support forum of your Octagon and ask there all your questions. Or wait for answer from any users having this model of receiver.
