In the recent review of the xonar ( http://www.silentpcreview.com/article913-page1.html )there was a comment on one of the messages boards about 24/192.

b) There is no difference at all for the vast majority of sources because 99% of sources are 48 / 16 releases anyway, so no downsampling occurs. Barring bugs or intentional quality degradation, the PCM audio from a Dolby TrueHD bitstream and the decoded PCM version should be identical for most discs out there. The users on the AVS forum thread for the HDAV1.3 had to go out of their way to find 96 kHz sources to test with.

So are a lot of movies just sample to 48/16 and then upscaled to 24/192? Does blu ray bring a better sound and more speakers or is it just the capability of better sound.
-Sound is pretty subjective medium for some reason-

I have two 24 bit 96khz Blurays/HD-DVDs. The rest are 48khz.
I have never come across a 192khz one, but I think there is at least *one*. I forget the name of it. I think the law-of-diminishing-returns has kicked in at 96kz...

Producers don't up-sample 16/48 source material to 24/96 or 24/192 for Blu-ray - there would be no value in doing so. The way the source material was recorded and mastered determines what resolution audio tracks will be included on the Blu-ray.
For movies and other long-form content, there would be little, if any value of going beyond 24/96. 24/192 would usually be a studio or live music recording, and probably then only in stereo. Mark's right - law of diminishing returns.
Blu-ray is definitely capable of far superior sound.
