I was wondering what the rest of you fellow tech-geeks out there think about the ongoing debate between DTS and Dolby Digital 5.1 decoding for DVD's... the reason being because I'm thinking about preordering the Jurassic Park / Lost World DVD collection, and since they are being released in both a DTS and a Dolby Digital format, which one I should get- and yes, both my DVD player AND reciever are DTS/Dolby Digital enabled, by that I mean my DVD player has a digital out for both DTS and Dolby Digital, and my reciever has both DTS and Dolby Digital decoders. One thing I know about DTS is that there aren't that many DVD's out there that are encoded in DTS- so far, all the DVD's that my friends and I have bought/rented have been encoded in Dolby Digital, with the exception of one music video DVD that my friend's dad bought, which was decoded in DTS. Also, what would be some good websites concerning DVD's and home theatres? Thanks in advanced... I look forward to hearing what you guys have to say...
DTS vs Dolby Digital 5.1 (AC-3)

Not sure exactly what the difference is, but i've heard both the dolby digital and the DTS version of saving private ryan and the DTS one definately sounds better, can't explain it, just does.

both are digital formats. both have the same number of channels.
the fact is, DTS uses a lower compression ratio which means better sounds. that is it. most people do not even hear the difference. on a high end speaker system, DTS is a must.
and THX certification is a good thing to look for.
dolby digital is the official sound format of DVD movies and DVD audio.

dolby digital is a must too.
so if you are an audiophile, you should already know this...
get a DVd player that has digital out for dolby digital AND DTS, and get a component that can decode both.

thx cert. is a waste of money. if you buy something with thx cert. good for you but don't make it a requirement for somthing you look for. nobody sees any thx certified krell gear do they?
anyway, there's because there is lower compression in dts, it means there is a higher "resolution", and yes there is a difference. most people will tell you that too, but that they can't describe what the diference is, but it's just there. that's because some of what is picked up is heard "subconsiously" as in they're everyday noises that the brain expects to be there but doesn't really notice it unless its not there.
like with cd's if you ask any audiophile, for the most part they'll say records sound better. i believe it was the nyquist theorem that said music needed to be sampled at twice the audible frequency - thus 44.1 on cd's. but it became apparent that there are certain intangibles that cd's don't have. ented dvd-a.

Just remember, the main difference between them is who did the audio mastering for the film.
The DTS version of Apollo 13 is worse than the DD version.
The reverse is true for Saving Private Ryan.
All depends on the movie.

out went dvd-a? it never even entered yet! imo it will definately be the format of the future. i just heard a demo of both that and sony's sacd (super audio cd). dvd-a blows it away. then i also listened to a regular cd compared to dvd-a. take my word for it, once it starts getting mainstream, it's here to stay.
btw, i auditioned all of this all on B&W matrix 801's powered by krell monoblocks, and a technics dvda player. oh wow.

Our DVD-Audio players have been on the market for a while now. We sell one under each label (Panasonic and Technics):

gtbuzz, that DVD-A player you listened to was from our Pure Sound line, which is the one we gear toward audiophiles. It's a beautiful component.
Basically, the sounds outside of the audible spectrum (for humans) can color the sound of tones we hear within the spectrum, so if the super-high frequencies are missing, things just don't sound the same. DVD-Audio supplies the extra storage space necessary to provide these higher frequencies, but only in 2-channel stereo. If you use all 6 channels, the fidelity isn't as high, but it's still quite a bit better than regular CD audio.

Wa-Hoo -- People with ears and knowledge. I'm glad I'm not the only one around here who knows about this stuff. 
YES, DTS sounds better because of its lower compression ratio. In the theatrical versions, Sony's SDDS is by far the worst. The difference is so stark that I will not pay to see a movie in that format. Of the other two, I strongly prefer DTS. For the theaters, it is more of a technical hassle, but it sounds better.
Unfortunately, in home systems, you probably need both, just to be able to play all the software you may want to see.
When Dolby Digital first came out, I attended Dolby's presentation for the AES (Audio Engineering Society), at the Acadamy's (as in Acadamy Awards) own screening room to show a comparison of various formats. They included all the old analog formats, too. The one that dusted everything by far was the original six-track magnetic stripe analog.
A couple of months later, they repeated the presentation for another professional group, which I also attended. This time, they omitted the analog six track mag film. They had a Q & A after the show, and I asked their sales director, Ioan Allen, about it, he denied that they had included it in the previous showing. This got a rousing round of hoots, because I was sitting with at least a half dozen other audio engineers who had been there with me.
Marketing -- SHEESH!!!
Regarding THX certification, again, in theatrical setups, you can actually call THX and complain if a theater that is THX certified is not living up to the hype. I would hope they put some serious teeth behind the consumer products, too.

I personally had a difficult time telling the difference for the most part. But I have very average speakers, so that's probably it.
i just wanted to let you all know i love home audio and theater. the first part of Saving Ryan Privates was and is awesome in dts. i havent heard it in DD, my friends are quite jealous they cant borrow my dts dvd for there DD systems. as a matter of fact, i am going to spin up that dvd and watch it all over again for the first time again. hehe.
btw, who's got the best set up here at anandtech?
