Not impossible, but not easy either.
I am open to ideas, but right now I am thinking of content that I know will test encoders such as complex animation with a lot of polygons and fast motion, good 65mm Film transfered to 1080/24P with a lot of detail, light & shadow areas, and darker areas with subtle shade and tone variations and also HD Video with CGI Overlays that have very complex detail and small moving CGI foreground elements layered against a 1080i HD Video Background.
I will probably use 192/24 and 96/24 soundtrack elements for the audio encodes. It will not be complex as in busy....it will be music with great dynamic range, tight bass, and clean highs with great depth, staging, and imaging in the mix. This is a good test for us since we are music guys and this is where the real differences can truly really be heard. However, we probably need to throw in a few things blowing up as well for the cinematic experience that most people are expecting.
We will max out the Birates for starters, even if we have go MOS (without SOund) and work our way down to real world numbers in the 22mbps to 24mpbs range, We might also do some tests at lower bitrates in the 13mbps to 16mbps range.
You are correct. No matter what, certain people will dismiss the tests and argue that the results are not valid...especially if it shows something they do not want to believe or accept. That is OK...and we are posting in this forum to minimize the chances of this...taking everyone's input and incorporating what we can that makes sense.
We will also mark the disc Version 1.0 so we can update and revise the disc as technology improves and as we get feedback from members.
I am still not sure if we are doing this yet, but I am leaning towardds doing it.

How would you pick clips (A/V). Obviously a totally silent part in a movie would be the perfect example of why DD = DD+ =DTS= DTHD = DTS HD MA = PCM or do you pick the most complex audio you can cretae and then show the differences just to get a response that "it does not matter if everyone can hear a differences 99% (used by some to mean most) of movies won't have something that complicated.
do you pick a video that will be better for MPEG AVC or VC-1 (each has its strength and weaknesses) how do you pick bitrate?
I guess what I am trying to say is that it is a sad fact but chances are people will find reasons to dismiss your test because it won't show what they want.
as for buying. Curiosity has me interested but what will be on the disk and how much it costs will be a factor.
