System, LG BD390 Blue ray, Onkyo TX-SR876 Receiver, 5.1 speaker set. HDMI hooked up. Can't get dolby trueHD to play. I know that it's got to be in the setting. I don't know what in best. Let the receiver do the decoding or the Blue ray and what settings. The receiver say's HDMI though when the blueray is playing. Thank's for any help.
