I have a macbook pro, so I can play 1080 through the VGA, or with my DVI to HDMI cable for testing computers, I have comcast dual tuner HD-dvr, and will have the $399 sony speaker system from their website. I also have a very nice (standard def) brand new camcorder, with firewire, and final cut pro on my computer, and my professional nikon d70 digital camera. (Sorry about listing off hardware). I also own a small hosting company, so I will gladly post, videos, photos, and any data you guys want
maybe now we can start listing off the things you want me to check when it arrives, a ordered list with instructions on how i can do the tests you want done would be great. I want to give back to the community since this place has been a valuable source of information regarding the choices of av gear I make.
So start making those lists for me! I'll setup a website at www.glancehere.com and get it all ready with the most relevant questions and tests listed, so I can just pop up the results, and gallery as soon as it arrives.
I'll make sure everyone gets lots of video footage of the set in action!!!! Hope I'm helpful,
all the best!

First order of business, determining just what the deal is with DRC and deinterlacing of 1080i. Do you know if the Macbook is able to output native 1080i over DVI? If so:
Grab the
VLC media player.
Grab this 1080i
test pattern.
Load the test pattern in VLC and set "Deinterlacing" to "Disabled".
Playback fullscreen with 1080i output to the DVI port.
Verify that the set is receiving a 1080i input
We're interesting in what the topmost set of lines does (1 pixel height alternating black + white)
If the lines remain distinct, then the set is doing a proper weave deinterlace and preserving the full 1080 lines of resolution.
If the block goes to a single color (black, white, or grey), the set is performing a blend deinterlace.
If the entire block starts flashing between white and black, it is performing a bob only, and discarding half the resolution.
If that works, grab
this version of the same pattern that adds a spinning "blade" to simulate motion. See whether the topmost block of lines performs the same as it did with the first pattern. Also of note is the behavior of the blade. May need to step through frame by frame to see the subtleties of this.
If it shows a double image of the blade that both display fine interlacing lines, the set is weaving.
If it shows a double image that are both solid (no interlacing lines), the set is blending.
If it shows a single solid image, the set is bobbing.
The ideal behavior that will indicate motion-adaptive deinterlacing would be for the top block of lines to remain distinct, while the blade shows as a single, solid image.
Finally, grab
this pattern that simulates telecined material without IVTC flags, and
this one for telecined material with IVTC flags. Look for the same types of behavior in both the topmost vertical bar and the blade. Again, proper 3:2 pulldown should result in the top block of lines remaining distinct, and the blade showing a single solid image as it moves.
