Could someone please refresh me on how to recreate DD 6.1 using two receivers. I have a Yamaha R-V1100 (DD5.1) and an old Yamaha RVX673 (Pro Logic) receivers. My thoughts were to simply run an RCA's from my DVD to the Pro Logic receiver and use only the rear effects from it. I question if this will work however as DVD's usually require you to differentiate whether you want DD or Surround so am not sure if I will still get the rear effects by running a DD signal into a Surround receiver. Thanks.
