Symptom: 1) During the multiple inputting mode (except Status 2/0/0

though the unit accepts the operation when the CINEMA EQ was set to ON at
the surround mode that consists of CINEMA EQ parameters such as PL II
CINEMA, etc.
2) In the PL II GAME Mode, the 10 msec. delay that is required to the Surround
Channel does not operate.

selected.
