i'm a 2-ch listener, even though i got a 7.1-ch receiver that does decoding of 5.1-ch LPCM via HDMI (it will interpolate the surrounds into surround back channels). i just don't have space to put any surround speakers.when i buy dvds, i always look for movies which offer 2-ch stereo soundtracks. soundstaging usually sound more opened than 5.1-ch, which suffers from phase cancellations in the downmixed process.
it seems all movie blu-ray titles will be releasing minimum 5.1 materials. are we destined to never enjoy optimum 2-ch sound plaback watching movies on blu-ray?

I'm inclined to agree. The use of the surrounds in my 5.1 system is essential and I look forward to expanding to 7.1.I don't have room either--I'd be surprised if you had less room than I. There's no chance I can set up my system to sit equidistant from all the speakers. But I make it work and use the delay setting on my preamp to ensure there is no smearing between the front and rear channels.
You really do need surrounds to take advantage of the 5.1 mixes that are as much a part of modern cinema (and remastered versions of old films) as the video.

blu-ray has transfer bitrate bandwidth of up to 54Mbps (someone correct me if i'm wrong). for video, the maximum allocated transfer bitrate bandwidth for video is up to 40 Mbps, but according to my authoring studio (which i'm working with on a blu-ray disc project), around 30Mbps would be sufficient enough to render good picture quality. it seems that a huge bulk of that remaining bandwidth would be needed to be allocated towards audio, since we are gonna encode 8-ch audio at uncompressed linear pcm, source from 96khz/24bit masters. they can still let me include 5.1 dolby digital and dts. but to include anything else extra like a separate 2-ch lpcm is out of the question, unless i don't mind to let the video quality suffers a little bit (no can do!). in one of the chapters, where picture quality is upmost importance, my creative team is reverting to 6-ch lpcm just to up the bandwidth for the video.but i'm destined never to enjoy surround at home. i just can't afford to have cables snaking around with my old folks at home. anyway, see u around 2 weeks time in sf. maybe if convenient, u might like to visit me while i'm in the authoring studio.
I guess they just figure you'll have 5.1. I do 2 channels too, but I just mix down the 5.1 to two. I haven't noticed any phase cancellations when I do so. In fact, I've compared the 5.1 (mixed to 2) Vs. the stereo soundtracks of quite a few DVDs, and I've always prefered the 5.1. On my system, I get better imaging with the 5.1, whereas the stereo sound hovers around the 2 speakers. I also get better extension at the extremes downmixing the 5.1. Its possible, that this is just due to my system (Bel Canto eVo 2i -> ESP Bodhrans + PSB sub). Needless to say, even though I also mix down my HD DVD soundtracks, they are still way better sounding than DVDs, especially the True HD soundtracks.

How do you mix down the 5.1 to two channels? I am using the new Samsung SP1200 Blue Ray player that I am now feeding via the two channel analog mix on the back of the player to a Spectral Model 20 preamp into the main CD imput.
