I've been watching quite a few movies lately and I've noticed that with DD 5.1 soundtracks the dialogue sounds much more clear compared to the DTS soundtrack on the same DVD. Have other people noticed this? I've always thought that DTS was supposed to sound better, but have not experienced this. Maybe my system isn't calibrated correctly? Anyone else notice this difference between DD and DTS?

Follow Ups:
into Paradigm Reference speakers.I've compared DTS to DD 5.1 on several DVDs in detail. DTS is always better, sometimes significantly so. Occasionally DD comes close.
A couple of good tests are the Tom Cruise cameo at the beginning of the second Austin Powers DVD, and, a Superbit version of 5th Element.
My receiver is a brand new Yamaha RX-V1500 which is mid-priced. I imagine it is up to the challenge of decoding both DD and DTS fairly well. In the few DTS discs I've tried, the center channel sounded muffled compared to the DD. Maybe I need to boost the CC in DTS mode and see if I like it better. A 1-2.0 db boost shouldn't screw up with the overall sound, would it? Also, maybe I need to play around with the dynamic range function and put it on MAX? Any other suggestions? Thanks.

I have a Yamaha receiver as well, although much older, and experience the same thing on the center channel. Using a calibration disk and SPL meter helped me figure out that there was an almost 6db drop in volume for the center. The muffled sound you're hearing could be a combination of the decreased center volume in addition to more information on all the other channels (from DTS).Playing with the settings (6db boost to the center) helped greatly, although this is a pain to set every time I rent a DTS disk, so I normally default to DD.
Hope that helps a little.
That's good information to know. I got the receiver right before the holidays so I haven't had the chance to do any calibrating with the spl meter. Does your receiver have built in test tones? Mine does and I was thinking about using these to calibrate the front three channels. But if it is a brand-specific problem, it's not that difficult for me to up the db's on the CC on this receiver. I can do it by the remote. Thanks.

I think it does, but I used the DD and DTS calibration from the Home Essentials setup disk. This showed that I had the drop on DTS, but not on DD. I set the SPL to 70db, which is where I usually watch movies at, then turned the volume up until L/R were at that level, then matched the center.
I can chime in with my observation that DTS has been significantly nicer sounding in all cases where I have made comparisons. I do have a fairly nice processor and DVD player, so perhaps this has something to do with it? I admittedly have just recently gotten the whole surround sound array in order and this comparison has only been made on, probably, five or six DVD's. I expect that there may be situations where the difference is nominal or tilted in the other direction but I have yet to find this to be so. I have noticed that DTS is also considerably louder with a greater dynamic range throughout.

If you were to rip a movie on your computer and look at the file size of the two soundtracks...the DTS file would always be the larger of the two.Larger file, more info. This would reason out that the DTS soundtrack should always sound better.
In the real world...this is not always the case. The DD may be the better (more to your taste)...or even better use of channel stearing that could make it sound better over-all.
More does not always mean better it would seem.

Doesnt your receiver decode the input, it does if you use a digital connection...In that case shouldnt be the players fault, but the receiver/processor that is not setup properly or doesnt work well...

I generally prefer DTS over DD and this is especially true with concert DVD's. DD channels through my speakers sound too distinct and 'disjointed' for music while with DTS I get a better enveloping surround that is more 'seemless'. Hard to describe but I do prefer DTS and this was with my Denon DVD-2900 before I sold it and with my present Denon DVD-5900.

I have not heard a different in front channel quality per se. What I do hear as a big difference is say on a street scene, dts has a continuous enveloping sound like reality. All channels are heard simultaneously. DD rear channels sound more like occasional sound effects (a plane flying from front to back or whatever), but does not have the continuous soundfield like reality.
I think you described it very well. I never paid close attention to DTS vs DD for movies but could never warm up to DD for concert DVD's. I've always preferred DTS as the entire presentation just sounded more natural.

I have found DTS 5.1superior in all cases. There is more coherence and more bass. This is not true regarding the competing matrix codecs (i.e., the ones that convert stereo to multi-channel sound) where Dolby Pro Logic II is superior to DTS Neo 6.Your problem may be with the DVD player or the processor, whichever reads the signal for 5.1
Well my dvd player is about 4 years old (Toshiba sd1600), so maybe I'm not experiencing DTS as I would with a newer/better player?
