Off – HDCD is treated as regular CD. This is useful when the player is connected to an
HDCD-capable A/V receiver via a digital audio output link (Coaxial, Optical, or HDMI) so the
A/V receiver can perform HDCD decoding.
NOTE
If your receiver is capable of HDCD decoding, it is recommended to set the "HDCD
Decoding" to "Off" on the BDP-93, otherwise you might occasionally hear pop or crackle
sounds during the HDCD playback.
