DTS does have the advantage that it uses less compression but can the average movie watcher tell the difference in sound quality? I certainly can't.

I can tell a slight difference, but I can't tell that one is better than the other...

DD 5.1 for me

absolutley..
its flat out night and day..

when I switch for instance Gladiator which has both DD and DTS once it kicks into DTS mode (your speakers MUST be able to decode it properly or it will sound identicle)
it is MUCH fuller much more vibrant.

its flat out night and day differnce..
DD is a poor mans format.. THX and DTS are for high end set ups that have the speakers and receivers certifed for them..
and the differnce is VERY noticeable.

What if your receiver decodes it and not your speakers?

speakers don't decode anything. they receive an analog signal from your receiver, which is probably the element that does the decoding. if there isn't a device in your signal chain that can decode a DTS stream, then you will get no output - not something equivalent to DD.

but yeah, i agree with th sentiment that DTS is noticably better than DD. switching between the two in Gladiator... i'm sure that even that most casual listener would be impressed.

it depends on your setup. If you have crappy radio shack speakers (or bose :evil: ) you probably won't be able to tell. Get some monitor or klipsch and it's night and day.

yeh thats kinda a typo..
but there are certain speaker sets (high end PC speakers) that also offer decoding.
but yes that should be reciever for most people.
just becasue the DVD player will OUTPUT DTS.. does not mean your receiver can DECODE dts.. in most cases it will force back down to DD which is why most people think there is no difference...

go to tweeter or another high end audio/HT shop and have them do both... you will hear the differnce..

'speaker sets' still have a receiver and decoder. the 'speakers' do no decoding.

Well, yes and no.

First of all, THX doesn't mean anything. It's just a certification and just because a company paid Lucasfilm for the THX cert doesn't mean it sounds any better or worse than something that isn't THX certified. And there are DD THX certified mixes done too.

Second, DD is not a "poor mans format". DTS does have a better theoretical sound quality, but it all comes down to how well the sound mix is done. In fact, on the Extended Edition of Lord of the Rings: The Two Towers, the DTS mix is actually very poor sounding. The DD mix is MUCH better.

There are some cases where you can easily tell the difference between DTS and DD, but it's not "night and day" generally unless something is messed up with the DD track.

the most that any DVD has is 8.x GB I think (on one side) so this is impossible. with enough extra features I'm sure you can fill up a DVD pretty quick.

on an unrelated note: i'm currently only running stereo through some hifi speakers but was thinking of dropping the big cash on the matching center. do most receivers support a 3.1 type setup?

The thing is though, when I've run all my DVDs thru DVD shrink, I don't think I've encountered more than 1 or 2 that cracked the 8 gig range. Most are 6-7 gigs.

bleh you know what I was trying to say... speaker sets dont have a reciever at all just an amp and a decoder for whatever formats are supported..

its not really proper to call it a reciever as in most cases there is no "box" just a sub with componants in it.

so its more aptly called a speaker set that can decode.

Licensing, additional production costs, no real financial incentive (How many people will refuse to buy a DVD because it doesn't have DTS? Even better, how many people know what DTS is?). WB is the worst offender.

I do agree that the gladiator DTS sound is much better than the DD, but some say that's because the DTS track was recorded "hotter" than the DD track was. It just sounds louder and better.

The difference isn't huge, and individual movies have varying qualities. The London Symphony Orchestra in DD 5.1 would sound better than me farting into a mic and recording it to DTS.

Well.. IMO on my setup even LOTR DTS kicks the crap outa the DD track..
it soudns hollow and tinny and all jumbled together compared to the seperation I get with the DTS tracks.

DD is the poor mans setup every setup out there as well as every DVD made has DD..
its the lowest common standard just like Prologic was...
it offers only the most basic features..

THX used to be much more than just a stamp they throw on things..
if you remeber the THX rating was only given to VERY exacting hardware and there was a THX decoding standard as well.
this has pretty much fallen to just a standard as you have pointed out now but in the past is was much bigger.

DTS is louder off-the-bat for me. I don't have to turn up my receiver as much. The sounds seems fuller, too. More of an intangible.

I imagine the DTS track on DVDs is probably the same one used in theaters. The DD downmix was probably intended for the living room. That's probably why switching from one to the other makes DTS sound 'fuller'. For most movies though, the DD will probably give you better dynamic range.
