What kind of connection are you using from the DVD player to the home theater decoder box? You have to make sure both it and the DVD player are communicating properly, such as looking for the fiberoptic output/input or coax if that is what you are using, 2-channel analog, whatever. Go through the DVD player's setup menu and see if it is set to output sound only on the HDMI cable, and change it to use both HDMI and whatever your link to the home theater decoder is.
Another thing to look for is the default output signal from the DVD Player - should be bitstream or PCM.
