That is all dependant on weather or not your receiver even does processing of the 5.1 input. If you can, give it a try. Turn on the 5.1 input and see if you can activate (

) a sound field, like Pro Logic IIx, or dts Neo 6. If you can, experiment and see what sounds good to you. In this relm, there is no correct answer of to process or not to process. It's all a matter of personal taste.
