New DVD-Audio music releases and talk about the latest players.

Re: My Panasonic F61A reads "PCM-dwnsmple" when playing DVD-As.

Your player is downsampling the hi-res audio (down to 48/16) for the SP/DIF port only. The digital audio going to the DACs is still hi-res, so you are hearing hi-res from your analog ports.

The digital is downsampled because of a flag set on the disc by the content owners so that hi-res audio (1) doesn't go out of an unsecure digital port, (2) conforms to the IEC 958 spec for bandwidth.

Newer DVDA players will support 1394 (Firewire) digital outputs to appropriate receivers.

Jim
