Marantz SR8002 7.1 Receiver Thread

[Streaker76]

Good day,

Question about decoding 7.1. I watched Hellboy 2 last night, DTS-HD 7.1. I have a 7.1 set-up. I'm bitstreaming the audio to my receiver ex Panasonic BD30. On my receiver display, the "S" is not illuminated. How do I know for sure that I'm decoding 7.1 audio on my receiver. I know that I'm decoding the audio by hearing the sound ex the back surrounds. Below is what stated in the manual about 7.1 with only a 5.1.

Manual
When this unit is decoding a Dolby True HD signal,
the status of the input signal is displayed, depending
on the number of speaker channels being used.
The “S” indicator is not illuminated when a 7.1-
channel signal is input to a 5.1-channel speaker system
with L, C, R, SL, SR, and SW.

Any input would be good.

Thanks
