I'v been buying alot of music dvd's as of late, and somehow, stereo sound better tha DD5.1, with the exception of some dvd's with DTS. So why is that?

Many reasons - you should first start with your equipment and check out the settings - what equipment do you use and what are they set at?

There is nothing wrong with my equipment. I'm talking about the fact that PCM stereo sounds alot better than DD5.1. The bass and the music comes alive, especially my fave music videos.

Sounds like its just a matter of taste to me. I like how 5.1 audio is produced more like a movie soundtrack with positional sounds, etc.. However, I don't think it's better then PCM, just different.

It could be because your front speakers are bigger/better than your surround ones.

I didn't mean that there may have been anything wrong with your equipment - just that there are so many variables - 'tis all....

CDs are uncompressed PCM, while DVDs use compressed audio in the form of Dolby etc.

That's what I thought. I just like the way two channel stereo sound on dvd's and cd's rather than 5.1. However, if the dvd has dts, I'd use it because it is not compressed audio. My fave is the Faith Hill DVD. Her song "Cry" made me want to sing with her!

Actually DTS is indeed compressed audio, just at a much better rate then Dolby Digital.

No it's not. If you read the booklet attached to any superbit dvd's, they show you the difference between dts and dolby digital, and why there aren't much room to put special features like interviews, deleted scenes, etc. on the same disc as the dts encoded movie disc. Which is why many dvd movies that has dts audio playback that also has a large amount of special features are divided into 2 discs. eg. Notting Hill Ultimate Edition, Spider-man movies, etc. Dts audio just takes up a lot of space on the one disc.

I found a website that might answer all your questions



DTS is compress lower than DD5.1, that's why it's got better sound
(check 1.32)
The Superbit utilize a high bit rate digital transfer process which optimizes video quality while offering a choice of both DTS and 5.1 Dolby Digital audio.

Superbit is nothing but a marketing ploy I'm afriad. But that's for another day. Wink

The only non-compressed audio available on DVD would be if it included PCM stereo, which is very rare on movie discs. In fact, the DTS on most Dolby Digital / DTS discs that includes both is compressed at 768 kbps, about half of what original DTS DVD releases alloted. Some swear by DTS, but personally I make up my mind on a title by title basis. I've heard Dolby tracks better then DTS and Vice Versa. It's usually all in the audio engineers mixing when they created the track.

Don't forget a true DTS experience is when they put a 1536 kbps track on a disc! Though usually at the end of the day, you may find an increased bit rate will not help if you have real cheap equipment....

Doesn't matter. I'm not a tech savvy and knowledgeable like all of you, sorry, and perhaps like my friends would say, I need to get out more.
Thank you all for sharing your insights on dts, DD and PCM stereo. I have just gained more interesting knowledge thanks to you all. I'll keep these in mind, the next time I check out a new disc with dts/DD/or PCM stereo. The stuff about DTs being compressed lesser than DD is new to me. Did not know that. Thanks. I now know it is just a marketing ploy.

C'mon, you guys are never too old to learn new tricks. You are armed with knowledge and experience that many of us don't have, and I thank you for that. Otherwise, I'd be stuck with the same equipment and what some home theatre companies want me to believe.
