Thanks, but unless I don't understand something, that doesn't answer the question.. The review article claims the following:
You’ll get the best sound by connecting the JVC to a modern HDMI receiver and selecting bitstream output for HD audio. Via PCM, the player only delivers the lower-bitrate, 5.1-channel core of DTS-HD signals.
The manual simply says "PCM 5.1" .... That doesn't indicate what audio is being used, the lossy "core" or the lossless 5.1 .... The note #3 says, "On the Multi-Ch PCM audio output, the sampling frequency of HDMI audio output is limited to 96 kHz or 48 kHz." Does that mean anything important?
