Hey all....Can anyone explain why BD movies (Specifically the LFE and dynamic range) sound so much better than DVD....even when in my case, I am playing them in standard DD and DTS?????. The difference is EXTREMELY noticeable to be honest ????!!!.
BD sound for movie's??

I would assume that is is because they do not need as much compression on the audio track since the blueray is so much bigger. Dolby and DTS are both lossy formats.. But I am not sure if like MP3 you can control the amount of loss at the expense of file size..Main System:
B&W 801D
Emotiva USP-1 Pre-Amp
Chord SPM-650 Stereo Amp
Oppo BDP-105
Squeezebox Touch
Second System:
B&W CM7
Emotiva UMC-1
Emotiva UPA-2
Oppo BDP-83SE
Grant Fidelity DAC-09

I'll tell you one small issue that sometimes comes into play. On legacy DVD's, most of the DTS tracks, and many Dolby, were produced with a lower bitrate. (really due to fize size) On BD's, they're full bitrate.
Example: My all-time favorite movie/video is U2's "Rattle and Hum". I'm very familiar with the material. When I bought it on HD-DVD, (and later BD) I could tell a better sound throughout the video, even though it's in DTS, JUST like the DVD. I even pointed this out to a lead Dolby engineer, and he said, "NO, there is NO difference in sound if it's still DD/DTS!" However, I pointed out that the HD-DVD/BD versions use full bitrate, so the sound is fuller and more detailed. He thought about it, and agreed. The difference is nowhere like going to lossless audio, but to me it was noticeable on my favorite movie/video.
Would any normal person notice on the average movie? I'm not sure.CHRIS
Well, we're safe for now. Thank goodness we're in a bowling alley.

Truth is for me, there is a HUGE difference between BD and DVD sound wise!!. When I load a movie in BD format (Via optical to my Rotel), and the previews load and play, it simply blows me away!!!. The overall dynamic range and LFE's are stunning!!!.Dan Madden :T- Bottom

Take the "Crossroads Eric Clapton Guitar Festival 2010" concert as an example.
Here's what you get on the Blu-ray disc for DTS:
DTS-HD Master Audio / 5.1 / 96 kHz / 8176 kbps / 24-bit and DTS Core 5.1 / 48 kHz / 1509 kbps / 24-bit
If you have older gear that can't decode DTS-HD Master Audio then you will be listening to the DTS Core at 5.1 / 48 kHz / 1509 kbps / 24-bit.
Compare that with what you get on the standard DVD disc for DTS:
DTS 5.1 / 48 kHz / 755 kbps / 16-bit
The Blu-ray disc has much higher resolution even if your equipment can't handle the new codecs.
