Hard 21 Posted April 18, 2004 Share Posted April 18, 2004 Some DVD's have DD on back and 5.1, others only have DD. Do these that only have DD on them do the effects of the 5.1? Quote Link to comment Share on other sites More sharing options...

So if it just has DD on the label it could be 2.0 or 5.1 or anything in between. To make sure you're getting all of the discrete channels, it should say DD 5.1 or Dolby Digital 5.1.

Darren Posted April 18, 2004 Share Posted April 18, 2004 I have about 250 DVD's (I live overseas and stock up everything I'm back in the states). Many say "DD", but are actually 5.1 sound. I guess it's a bit of a gamble, but I haven't bought any DVD's that didn't have at least one 5.1 option (all have DD 5.1, many also have DTS).

Hard 21 Posted April 19, 2004 Author Share Posted April 19, 2004 What's the difference in DD 5.1 and DTS? In layman's terms. Just a breif little description please, unless one wants to elaborate. Quote Link to comment Share on other sites More sharing options...
TBrennan Posted April 19, 2004 Share Posted April 19, 2004 Some DD discs are mono, which is cool. Quote Link to comment Share on other sites More sharing options...
ygmn Posted April 19, 2004 Share Posted April 19, 2004 DD 5.1 is from DOLBY LABS inc and is one type of audio compression DTS is from a DTS inc and is a different type of audio compression... both companies work with the movie industry.... Check each website for more info I prefer DTS sound tracks...but that is me Quote Link to comment Share on other sites More sharing options...
Thors1982 Posted April 19, 2004 Share Posted April 19, 2004 Just cause a DVD says Dolby Digital does not mean its 5.1, could be 2.0, but in general most of the time it is 5.1. In fact just because it says Dolby Digital doesn't even mean its Dolby digital, could be Pro-Logic. Quote Link to comment Share on other sites More sharing options...

I was very disappointed with the sound. Very weak effects. Two things came out of that thread. Someone mentioned that the DD 5.1 sounded much better than the DTS, & I confirmed that on my disk. Many others said the DTS sound track was awesome. Even different magazines had opposing opinions. Turns out, there were 2 different pressings of the disk, & half (like mine) got a bad DTS track. A good example is on track 11, the cannon shots sound like pop guns on DTS, but shake the room on DD 5.1. Point is, I learned to play both the DD 5.1 & the DTS to see which is better.

m00n Posted April 19, 2004 Share Posted April 19, 2004 cyclonecj, is there a way to find out of you got a bad DVD other than just listening to that one chapter? Is there any kind of marking or serial number range to watch out for? Quote Link to comment Share on other sites More sharing options...
cyclonecj Posted April 20, 2004 Share Posted April 20, 2004 Actually, the whole disk sounds weak on the DTS setting, not just the one chapter. I just used that one chapter for an example. The article I read about the 2 different pressings did not identify who was who, other than there were 2 different pressings. It was written after a number of complaints about the sound were received. I just looked & cant find the article. Probably could have been bad news for the publishers of the bad version. I should have saved it. Quote Link to comment Share on other sites More sharing options...
doudou Posted April 20, 2004 Share Posted April 20, 2004 i ve an old dvd in DD and it s some 3.0. in fact it seems that DD can be almost anything from 1.0 to 5.1 Quote Link to comment Share on other sites More sharing options...
Darren Posted April 20, 2004 Share Posted April 20, 2004 The Pirates of the Caribbean reference is the first I've heard of a bad pressing (in DTS or DD). I've read DTS is less compressed and generally has better sound. I've compared in several movies and couldn't conclude that either was consistently better. Also a reference above that Dolby Digital could be Dolby Pro-logic. This shouldn't be the case, but I've found some of these myself (all older movies). I've assumed the boxes were mis-labeled, but that didn't make me any more happy about it. Quote Link to comment Share on other sites More sharing options...
doudou Posted April 20, 2004 Share Posted April 20, 2004 DTS has a larger dynamic range(about 120 dB) than the Dolby digital(100 dB if i remember well). so with DD the loudest sound should be 100dB versus 120dB with the DTS. it seems to be the only difference on quality.if most people don t notice the difference it s because we don t often watch a movie so loud, and if we do the 120 d peak is not reach very often(only with some special effects like explosions,...)

doudou Posted April 20, 2004 Share Posted April 20, 2004 and i ve took a look on the dolby web site, it seems that dolby digital id 5.1. so my old dvd with DD in 3.0 should be dolby prologic plus a mistake on the dvd box Quote Link to comment Share on other sites More sharing options...

If it is 2.0 then it it is pro logic. Just because it has DD on it does not mean it it is dolby digital. It is just dolby (the companies) symbol. one forward d then one backward d. i found a link to decribe the difference. http://dolby.custhelp.com/cgi-bin/dolby.cfg/php/enduser/std_adp.php?p_sid=Pq7LDl9h&p_lva=&p_faqid=136&p_created=1015027785&p_sp=cF9zcmNoPSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9NzcmcF9wYWdlPTE*&p_li= to see if the disc has 5.1. i would believe that would be wrtten on the box, I don't really pay attention. i thought all dvd's a least with movies made now days. were in 5.1. now older movies may not be unless digitally remastered Quote Link to comment Share on other sites More sharing options...
