Make sure your DVD player is outputting PCM if using an HDMI cable or 5.1/7.1 analog connections to your reciver. If you are using an optical Toshlink or digital coaxial audio connection, then make sure you are NOT using PCM in the player, but rather set it to bitstream. If this is not set right, then you will not get the correct surround and sub output. Hopefully your receiver has an indicator to confirm if it is decoding the correct multi-channel signal.
