Thanks, that's about what I figured but not really sure!
The other thing that I can't seem to find out though...
The manual talks about 3 positions of the LEDs. It says that if DTS/Dolby are detected, the LEDs will light up in Position 1.
I'm assuming that Position 1 is underneath the DTS/Dolby logo? But nothing seems to come on under that. I have my optical cable now, and still nothing.
What I have are, from L to R, a blue light, blue light, orange light. I think that the orange light is the power light/subwoofer linked light. So basically it sounds like the DST light isn't coming on for some reason.
