So if the TV screen or the movie image is 1 feet tall 3PH means sitting at 3 feet away (eyeball is 3 feet away from the screen) 4PH is 4 times etc. Since movies are suposed to be watched at the same height (it's their width that changes on screen), PH is used as viewing distance measurement, instead of the home theaterish screen widths

The TAP (Theater Alignment Program) guidelines specify seating distances of 1.4PH from the good front rows to 3.6PH for the bad very last row at the back of the theater. (For example if you seat in the middle of a theater designed that way you are at 1.8PH)

(Heh I love it when manufacturers recommend sitting distances more apt for watching DVDs, with 1080p displays)

ok you are at 96" from your screen.
Your screen is 27" x 49"

You watch 1.33 and 1.78 at 3.6PH and you watch 2.39 Scope movies at 4.8PH

So for 1.33-1.78 movies you are watching like seating from the last row of a theater (And for Scope you're much farther away)

I watched DVDs that way.

They are there, you're just sitting to far away to see them. If I sit and watch Lethal Weapon 2 at the same PH distance as you I can barely see it too (1080p direct view LCD (no lens) set, 1:1 pixel mapping, 0% overscan)

There's nothing wrong with his system he's just seeing what's there, like Brad and Chad and I and others see.

There's also nothing wrong with your system, you're too far away to see it, and also, your Display is projecting the DLP through an (internal) lens, which tends to smooth out the "squarewave-like" jaggies, or actually, "limited horizontal resolution" pixels, in this case.

mm ok maybe the easiest way to see this is to look at the black and white (white letters on black background)

WARNER BROS.
presents

logo before it says Lethal Weapon 2 at the title credits in the beginning.

Warner Bros. presents is in all its horizontally pixelated glory. On a 1080p direct view you probably can see it from even at 3 PH from the Scope height! (5 feet on your case)

Sit at 3 or 4 feet and look at the logo, or at any high brightness highlights/edges thoughout the movie.

For example look at the scene starting at 10:10, on the middle right of the background there's a window filled with white light. There are two vertical bars (run up and down) in that window that seem to each occupy two actual pixels in width but are imaged at just one pixel that's upscaled onto two pixels wide and as the camera or film moves or weaves left or right you can see the bars jump from 2 pixel slot to 2 pixel slot instead of smooth pixel to pixel motion.

Warning: once you see these things you might not b eable to not see them afterwards!

Well it's not aliasing, it's just looks as if the transfer seems to be something transfered in 1080 x 960 pixels, interpolated to 1080 x 1920 by multiplying the horizontal pixels 2x to make them 1920 wide. The vertical 1080 lines are smooth. The horizontal detail on the other hand, looks like it's about 2x pixelated (twice as thick as it should be. or half the lines) Maybe it's a 1080 x 1440 master or something.

In that particular scene (1:10:38) all the blinds are practically horizontally aligned, (so they go left to right so there's no horizontal resolution components lines) (lines that go up and down vertically) so there's no pixels to be doubled. As I said the vertical resolution of the transfrer is smooth and fine, it's the horizontal resolution that's doubled or pixelated.

Apart from that, the transfer is nice and clean and colorful, looks like if made from the original Scope neg, and with 100% of its 2.40 height (you can almost see the splices go by on scene changes!), scenes shot in sunlight look breathtaking (look at the shot on the beach at 1:10:24 wow) I think it looks great.

The transfer is a high bit-rate VC-1 (about 23 Mb/s) so maybe this was a way of achieving such a clear image when using VC-1 at the beggining of their VC-1 transfers: encode half the resolution to make a 1080 x 960 23 Mb/s look as clean as a 1080 x 1960 46 Mb/s transfer (which they can't do), and hope that MTF losses from projector lenses (or 720p panels) and normal (for DVD) viewing distances smoothed out and turned square wave pixels into smooth sine waves (which is what starts to happen when you pass a "square wave" though a lens) or the high frequency bandwidth of the display's video amplifier has a roll off (same difference) and hope nobody noticed.

Except, that you can't watch it projected on a big screen because of the pixelation (Something that is a piece of cake for other Blu-rays!)
