Ok... Let me try to answer all those questions. :)
jmwfl2000 -> The black levels are some of the best LCD ones I've seen, which would confirm the difference between the 600:1 and the 500:1 CR. Though it is still an LCDs display and it doesn't compare with my DLP PJ I've got downstairs. I'll still have to calibrate it to get the best performance. Also, I can't guarantee pictures, but I'll see what I can do.
bshplt -> Just like the Maxent, there is no ghosting/streaking, 16ms seems to do the trick pretty well. I've only tried the unit with my Mot6200 Cable box, but I did try the override 480I option on it. The deinterlacer was looking as good as the one that's in the Mot6200 (average, nothing great there). Standard cable through the cable box looked somewhat more grainy and noisy than the Maxent I had. I'll try plugging cable right in to see what the tuner looks like and let you know.
Beckles -> If you're watching Fox, PBS and/or ESPN on HD Cable right now, you'll find out that, sometimes, those channels will stretch some 4:3 content into the standard 16:9 HD aspect ratio (they don't window box), thus screwing up the AR. That's very annoying if your TV doesn't let you squish the image from a 16:9 format into a 4:3 to correct the AR. That feature is what I called "4:3 stretch" for lack of a better term. BTW, the unit doesn't seem to support any other kind of zooming or stretching. So, we'll have to live with double-boxed content (letter-boxed + window-boxed) sometimes. The Maxent had like 6 different stretching/zooming options, so I feel a little bit short-handed on this issue.
TauRus -> Please read comment above. Also, from the testing I've done so far, the unit seems to be following the right AR for all modes. The "4:3 stretch" was not available on the Component inputs (only on DVI so far, I didn't try cable/SVideo/Composite) and would probably be to fix a problem with the source itself or maybe for the upscale DVD case that you talked about (DVI connected DVD trying to display 4:3).
Anybody else got it yet?
