This thread is a reply to:

but took on a life of its own =). the topic of discussion is will consumers (avg. joe) know the PQ between the various resolutions? the answer to this will determine the sales/results of th war between HD-DVD&BR&SD-DVD. it's not only 2-sided. it's 3-sided.
i took the 1080p (816p actual) mi3 trailers from quicktime.com and made a screen cap. here's the original:

assuming that this is a ratio of 7680x4320, i used photoshop to downres from the 816p file and produced the following:

assume that these 4 different resolution sizes are the SD, 2k HD, 4k HD and 8k UD masters. these 4 files are the "baseline" for comparisons.
but nils already did that in the above thread. what i wanted to find out is how the resolutions look in relation to one another when you view it on the same sized display/screen. therefore, i upscaled the lower resolutions (equivalent of their various mediums) to highest definition and compared it all. let's assume that this is being projected on a 108' diagonal IMAX screen (where this is the most difference):

now, let's scale that baby down to 10' diagonal (home resolution). the original 816p's diagonal pixel is 2086 (approximately). so 2086/10=208.6. a home projector would be about 10x less than an IMAX projection. i took each of the 4 different "masters" and downresed it to the home projector equivalent:

before you jump on how you can't see anything (this is all to a consistent scale), let's compare it to a regular cinemas' size (so you can see the diff). a cinema's screen size is about half the diagonal size of IMAX. i took the 4 "masters" and scaled it to that size, so here it is:
