I'm using an analogue connection with my DVD player (haven't bought the digital coax yet). It sounds super in stereo mode. I even set up the dolby/DTS/CS2 etc, but nothing happens when I turn the big surround knob. It remains on stereo. It works with the remote but not manually. Help please!!
P.S.: I've posted this messageelsewhere too but nobody's replying.
If I were you I'd call the Marantz tech support line, they should be able to walk you through it and see if it might be a factory defect.
Have you looked in the manual? IIRC on my 5400 there's a button or two under the knob to set it's function.
I'd go with bumblebee's suggestion. In all probability, you're using the 5.1 out of the DVD player & connecting the same to the 5.1 in of the 4400. In this case, you need to use the 5.1 input mode (not auto) on the 4400. Also check if you've enabled 2-channel downmix on the DVD player, tho I don't think so, 'cause then it wouldn't work with the remote.
In either case, I'd suggest you to go pick up a digital cable & end your problems altogether...
