This might sound like a stupid question but now that I got a new dvd player and now here a different sound on dvd movies brought me to this question. My old player was a JVC XV-723GD unit. In the setup menu for it, it gave me the option for DD and DTS bitstream or just PCM for DD and DTS. Well I set it to the bitstream and got no audio,then I set it to PCM and got the audio for DTS and DD. Did I set it up properly? I just bought a Denon 1600 and selected Bitstream for both DTS and DD. The sound out of the Denon sounds a lot better now. More open and very detailed, however I have noticed that I have lost some of the low frequency impact that I had with my JVC. What could cause this?
