Hello everyone. I just had ATT U-verse installed today and its been great so far. It is connected to my Denon 2808 receiver via HDMI cable. I typically keep the receiver on Direct mode and my understanding is that in this mode it will decode whatever the input singal is. Standard shows are usually in 2 channel stereo in this mode. The problem is when I put it on HBO HD, I am not getting 5.1 surround sound. I'm pretty sure the channel is broadcast in 5.1. Do I have to change my receiver to the Dolby Digital surround mode everytime? I figured it would automatically decode the signal. Am I using the wrong the mode?
