N About DTS signals
When DTS program material ends and the DTS
bitstream stops, the AV receiver remains in DTS
listening mode and the DTS indicator remains on.
This is to prevent noise when you use the pause, fast
forward, or fast reverse function on your player. If
you switch your player from DTS to PCM, because
the AV receiver does not switch formats
immediately, you may not hear any sound, in which
case you should stop your player for about three
seconds, and then resume playback.

Playing DTS program material, using the pause, fast --
forward, or fast reverse function on your player may
produce a short audible noise. This is not a
malfunction.
N The beginning of audio received by an HDMI IN
can't be heard
Since it takes longer to identify the format of an
HDMI signal than it does for other digital audio
signals, audio output may not start immediately.
