Actually I am confuse too. In fact when I listen to DTS HD on BD & DTS on DVD it sound the same to me!    BY right should be better!? Something wrong with my BD30 set-up???
Panny BD30 HDMI to Onkyo 875 HDMI in. Onkyo 7.1 set-up ( normal cheapo speaker  ) Panny BD30 audio setting all set to bistream, secondary audio set to off.
Thank in advance for all advice! Have a very nice day!

I suppose my ear is still not yet HD!!!   But I do notice on my 875 display it show all the spk like L,R,CENTRE,SURL,SURR & LFE ( SUB WOOFER ) but the SBL & SBR not light up which seem to meant the source is a 5.1 even when I am watching BD. I thought all BD is in 7.1??? Anyone got AV showing all the 7.1 when watching bd?

BTW tq for all the expert answer!   Have a very nice day!

dirtrun, marantz 7002 doesnt have the TrueHD/DTS-MA light to tell you if these audio track is on or not.

So that real life Joe will never get himself into home theater hobby in the first place don't you think? Why bother to spend thousands of ringgit on speakers, subwoofers, and receivers if you can't even tell what you're hearing?

Tell you what, even my wife can tell the difference, the only reason I'm allowed to continue on this expensive hobby.

And I totally disagree, audio is NOT just icing on the cake. Audio represents 50% of movie watching experience. I'm sure you wouldn't want to watch Live Free or Die Hard using your TV's puny stereo speakers.

As far as home audio goes, it's already the best we can get in terms of details, because it's already lossless, meaning bit-by-bit identical to the studio masters. The only way to improve now is the studio remix it to 11 channels, or make separate tracks for music, dialogue, explosions, and background to make it as pure as possible and let the future receivers to mix it onboard (crazy idea ).

For picture, the film masters are scanned and transferred to digital at 4k (2160p) resolution, that is double the resolution of blu-ray (1080p), and your TV! It then downscaled to 1080p before transferring to blu-ray. For digitally shot movies (i.e. Crank), 1080p is the highest they can go, because they are shot natively at that resolution.

So, I'm not worried about blu-ray, a 400GB blu-ray has already been developed. I'm much more worried about our display (TV, projectors, etc), which the highest resolution can be found now is only 1080p.

PS: Dirtrun, you watch your movies blindfolded?

One more thing, you receiver won't lights up DTS-HD MA or Dolby TrueHD when your PS3 already decodes it. The receiver already receives it as PCM, there's no way it could tell the format. So yes, you don't need a receiver with DTS-HD MA or Dolby TrueHD onboard decoding, the PS3 already done it for you. All you need is HDMI input with mulit-channel PCM capability.
