Interesting because, from the few movies that I've watched, it seemed that DTS 5.1 or Master HD sounded better, or should I say, had more impact than Dolby Digital or TrueHD. But I agree that NEO6 sounds odd, for me specially on the vocals (ie the "echo"). I also didn't know that you could apply DPLII to DTS 5.1, I thought is was only for 2 ch stereo, I'll need to try that. I'll also need to look deeper, and maybe try to understand my Denon's manual :), and try to find where I can change these parameters (dimension, width, etc..) as I haven't found it so far.

DTS had (as in the past) a lossy compression scheme that allowed for 1.5 Mbps of the DVD's mux rate to be allocated to audio. That often wasn't used because there still had to be a DD (or PCM, but that'd be stupid) track, as DTS was an optional part of the spec. 1.5 Mbps plus at least 256k for the backup DD (and each additional language) was too much for most to give up. But the 1.5 Mbps DTS was the best sounding audio available on DVD.
In order to be more accepted DTS made a 768 kbps variant of their codec. While it still sounded good, it was obvious why DTS sounded better than DD with it's 384 kbps rate. Their algorithm just wasn't as good at compressing, but still benefited much from the larger bandwidth allocation.
When it comes to the modern TrueHD vs HD Master Audio, there is no difference. They are both lossless. Studio's seem to prefer DTS's offering, maybe because their name still makes people think they are getting more.
PLII can't be applied to 5.1 sources. But PLIIx can be used to turn 5.1 to 7.1. When I have PLIIx set, and feed my receiver 7.1 audio, it also turns off, just as PLII would turn off for a 5.1 feed.

Thanks Chris for the explanation. The only thing I still don't understand is that you say that DTS was the best sounding audio on DVD but you still prefer Dolby? Or is it just that you prefer DPLII over Neo6?

The latter, I prefer Dolby's ambiance extraction/channel expansion to DTS's. That is to say, I like the way Prologic sounds more than Neo:6.
So if I have a DVD or BD with a DTS 5.1 soundtrack I'll pick it for playback, but processed with PLIIx to make it 7.1, rather than Neo:6.

Heh. I prefer Neo6. DPLII just sounds muddy to me. If I actually got around to setting the channel levels on it, I'd probably use Logic 7, though.

So I got my replacement and everything seems to be fine with it. My only concern is the crossover level set by Audyssey. At first, I only ran it for 1 position just for a quick listening. It set the crossover at 200Hz. Then I ran Audyssey for the 6 positions and it set it a 150Hz.
My room is 20x11 ft, hardwood floor, high pile rug in the center, 2 bay windows with no curtains just blinds and not too much hanging from the wall (I know, far from ideal). My TV is wall-mounted at the center of one of the long wall, my couch is against the opposite wall (actually about 70% of the couch is against the wall and 30% has one of the bay windows behind). The QS8s are wall mounted with the T-bracket on my back wall, each about 7ft from the main listening position and and the tweeters are about 2ft above ear level. Since my couch is against the wall, they are very slightly behind me.
Questions:
1) Could the fact that the bottom driver is so low be the reason for this 150Hz crossover? Not enough distance for the sound to spread?
2) Does anybody has had Audyssey cross over the QS8s that high?
3) The QS8s should be able to play 100Hz. So if I manually set the crossover to 100Hz, does it mean that Audyssey will just not apply EQ between 100Hz and 150Hz, or the QS8s can simply not play anything below 150Hz in my room?

If you lower the crossover from where Audyssey performed it's measurements, you'll just get a linear EQ applied (i.e. no EQing) below the original EQ point. The speakers will play those frequencies.

Still odd to have your QS8's being set that high but I would suspect it is just your room/speaker placement causing an issue.
With Audyssey setting the crossover that high simply means it is seeing a substantial drop off below that frequency from the QS8's so it wants to send anything below that crossover(rolled off not a brick wall) to the sub. Since this is just a surround channel I wouldn't worry too much about dropping that crossover on them to 100 or even 80.
I would suggest having a listen at all crossover points from 80 to 150 and then go with the one you liked the best.
