Below those 2 in the speaker map area I have the front left and front right channels and a rear-center-surround.
I just tried this out on my 8400. This is entirely normal for a Dolby Surround track. Yes, there should be a C channel, but there isn't on the diagram. Doesn't matter, your C channel should be working perfectly.
The "S" channel denotes surround. In a Dolby Surround 4.0 track, you have L, C, R and mono
surrounds. Dolby Pro-Logic will decode the surrounds as mono. Dolby Pro-Logic II will decode the surrounds as stereo. Dolby Pro-Logic IIx
will steer this sound over the 4 speakers. (SL, SBL, SBR, SR). So a Dolby Surround soundtrack decoded with the "original" decoder for Dolby Surround (Dolby Pro-Logic) would have the surrounds in mono - hence only one surround, "S".
This does not mean those speakers aren't active - this is just the data that's being read off the disc.
Back of the DVD case says: "AUDIO: English 5.1 Dolby Surround, English Dolby Surround". Nothing about a French track at all. There's even a Dolby DIGITAL trademark next to the PG-13 rating.
They are tricky, no doubt about that. But if they say "5.1 Dolby Surround" it's actually Dolby Surround, which can be decoded as 5.0 with Dolby Pro-Logic II and 7.0 with Pro-Logic IIx
. Not discrete though, and there is no ".1" track with Dolby Surround.
Note they did not say "Dolby Digital 5.1". If they don't specifically say Dolby Digital 5.1 it isn't in DD 5.1.
It's considered Dolby Digital 2.0 - and in fact, your DVD player may label the track as such. It should say "ENG1 [double-D] 2.0 CH". That does mean you get to benefit from the increased dynamic range DD has to offer. And with a digital source, channel separation is VERY good.
So your receiver is operating fine, your DVD player is operating fine, but your DVD isn't quite what you expected.
I'll work on getting some digicam shots of my receiver display with different formats.
