Dolby Digital/DTS

I just purchased a RM6000 system and have just been using the analog audio outputs from my DVD player and using Pro Logic II on my reciever. However, I just purchased a coaxial digital cable and have hooked that up to the digital out on my DVD and to the digital in on my reciever. My receiver has an autodetect feature that selects whether the signal is digital or not (A Kenwood VR-507.) I can set it to DTS or Digital but for some reason the surrounds will not work. If I go in and change the audio output on my DVD player from PCM to bitstream the reciever chooses DTS but surrounds won't work. They show as on when I go through setup, but no sound comes out. If I change my DVD audio out back to PCM my reciever shows a digital signal but the surrounds will only work when I choose Pro Logic II mode, and will not work in DTS or Dolby Digital mode. Pro Logic II mode sounds good, but DTS and Dolby Digital sound way better. Any ideas? I am stumped, maybe I am missing something. This is a weird one. Thanks.

    Sorry to reply to myself, but I had one more question. What is the difference between PCM and Bitstream on the DVD audio out anyway? And which one should I use? Thanks!!

    PCM is what is used for analog signal. Bitstream is used for the digital connection for use with DTS and Dolby Digital.

    If you have both the DVD player and receiver set to bitstream you should not be having any problems, but I really do not know the setup of the receiver. Have you tried this with a Dolby Digital DVD? Like I said I really do not know the Kenwood, but most receivers display the type of signal coming via the digital connection (Dolby Digital, DTS or PCM). You are saying you see DTS. Have you also tried disconnecting the analog connection from your receiver? I know this is not much, but good luck.

    Hi:

    Did you go into the setup on your DVD player and set it up for digital output? I had to on mine, a Sony. If you haven't, it will not send the 5-1 output to your receiver.

    I believe PCM stands for pulse code modulation.

    Go into your DVD setup menu and follow the instructions on how to set it up for coxial output and I believe you will solve all your problems. Let me know if this solves your problem.

    Also, did you go into your receivers audio setup and tell it that you were using a coaxial input from your DVD? I have a Denon 4802 and you have to assign what type of input you have for the DVD. I believe all of your problems are setup related and not being familiar with your receiver that is all I can tell you.

    I believe I got it, and it was a setup problem. I don't have my analog outputs hooked up anymore, just analog audio from my cable box. I have my DVD player set to bitstream and the reciever picks up the digital signal and everything is working. It sounds good. The reciever now has a little light on the display that says "downmix" when I play a DVD. I can't find in the book what this means, but oh well, it is working good now. Thanks for all of your help!

    I don't think you should have a "downmix" light on your receiver if you are listening to Dolby Digital. Downmixing means that it may take the Dolby Digital or DTS signal and mix it down to two channels or to pro logic or something other than Dolby Digital. Hmmm? very strange. check settings once again to see if somewhere in the menu set up it has a way to turn off the downmix. are you getting sound from all speakers?
    good luck.

    Thanks for the info. I am going to check on Kenwood's website. It has the downmix indicator but it also has the 5.1 indicator light on as well. With the front left and right, center, surround left and right and the LFE channel.
