Greetings: Hope I am in the correct forum. Samsung HT-2420 is a 5.1 system with a built in DVD player. I am hooked up to a Vizio 55'' LCD using optical connection to Samsung for audio. The built in DVD player gets all 5.1 channels, and the TV plays all 5.1 channels through the Samsung receiver. However, I have 2 DVRs (DTV Pal DVR) a DVDR with built in tuner and a DVD player all connected to the TV using HDMI. The Samsung receiver isn't putting out all 5.1 channels from these sources, only 2.1. None of these sources have optical out connectors, only HDMI, Component and RCA. Input to DVRs, TV and DVDR are all OTA. I am thinking that the TV should pass through all 5.1 channels from these external sources. Is my thinking flawed? Should I be getting 5.1 output from the Samsung for these external inputs?
