Yes, basically you have it correct. The receiver is just getting Right and Left from the TV. To get the surround sound, the old Kenwood is doing processing.

What I suspect is happening on the HD channels is that the audio is multichannel audio. The TV is "processing" it and then producing Right and Left for the outputs. Then, the receiver is taking the Right and Left and "processing" it again for surround. In the double processing, something is getting confused.

I really have no idea what algorithms are used.

But, in any case, it only does it on the HD channels.
