Since the above did not work, your situation sure sounds like an issue with your receiver with the encoding. I unfortunatly can't help with that. Their might be someone on here that might reply, but it might be a good idea to call the manufacturer of the receiver and see if they can troubleshoot some things for you.
We have a Yamaha AV receiver that has various surround selections. It is connected to the DVR via R/L auto. The TV is connected via HDMI. It's not just that we are not getting surround but you cannot hear the voices if the stereo is set to anything other then straight Stereo. If I tune to the non HD channel of the same network (2, 4, 7...) it works, that is we hear the voices.
Our stereo has a simulates surround but that does not work on the HD channels either.

What cable or cables are you using to hook the receiver up to the dvr? Are you using a optical digital, coaxial digital or are you using audio wires (red/white or composite) ?
