i have a few dvd movies with terrible sound and i have to turn the volume way up to be able to hear it and i have great hearing too so i was wondering when blu ray finally arrives will it have great sound or will it suffer from bad sound like dvds

Blu ray is video, really nothing to do with the audio although usually if the video company did a good job with the video they did a good job with the audio.

Can you provide more information on the audio specs of the release. Were they THX, Dolby audio etc. How many channels?

There are three possibilities. The sound on the releases are terrible. Your system sucks for sound. Your system is set up wrong.

And there's also the fact that DVD has a wider dynamic range than other mediums, which is why you'll generally have to increase the volume to match say TV programs that are coming out of the same source. That's a trait, not a fault, of DVD audio in general.

Well DVD's DolbyDigital sound is compressed 10-13 times (just like, or worse, than a 128kbs mp3) but that has nothing to do with low volume audio on your DVDs.

Blu-ray with its 50 GB capacity and more coming later, won't need to have compressed audio cus it has lots of space (but will include the tiny DolbyDigital sound file for compability with all current receivers)

There are several uncompressed audio formats for Blu-ray. One described by Dolby, DolbyHD includes 8 channels of uncompressed audio at 24bits/96kHz per channel (CDs are 2 uncompressed channels at 16bits/44.1kHz per channel). DolbyDigital on DVD has 5.1 channels of slightly better than CD specs but as i said, it then compresses that data 10-13 times smaller than its original size. But again none of this would affect overall volume levels.

Moving this to off topic.

I have the same problem with the tv shows on DVD.
