Most concert DVDs do have 24 bit PCM tracks. Some are 24/96, some are 24/192, and some are just 16 bits. Sometimes it's not labeled well on the box and you just need to pop the disc and select audio menu to see which tracks are available. DVD players will almost always choose Dolby Digital track as the default, and that's what will be playing if you just hit play. I think two channel PCM is also required in all DVDs but I'm not 100% sure about that.
Laserdisc Dynamics vs Blu Ray
I've done a lot of research lately on the merits of Laserdisc. A number of people have suggested that a Dolby PCM Surround track sounds much better then DVD and even in some respects better then Blu Ray.
I understand the DVD vs Laserdisc comparison because of the resolution and lack of compression found on Laserdisc in Dolby PCM and even DTS. What I've found interesting is that Laserdisc used Theatrical Audio Cuts while DVD and Blu Ray use watered down Studio mixes for the home. The theory being that many users will use cheaper speakers and television's as their primary audio sources. A Theatrical Audio cut offers dynamics most systems couldn't endure, therefore the mix down.
Can anybody share experiences? Has anybody compared a Lossless Blu Ray presentation vs an older Laserdisc Dolby Surround cut on a decent setup?
