From the sample, I noticed that the image looked a little soft-contrasted. When I checked, it showed a used range of 16-235 rather than the expected 0-255.

Shouldn't the capture and/or the final file have been the full range? I know the old analog broadcasting required 16-235 for safe NTSC transimission (although JP standards allowed 0-235 for their version of NTSC), but in digital media, shouldn't it have been 0-255?

.

Also, grabbing a screenshot (no aspect ratio compensation), I noticed it looked very "thin". Normally, a raw screenshot would come out looking a little "fat".

For a flat-widescreen frame like this one, the picture area itself should've come out 720x316 (as it does on a remaining US/JP screenshot from the other THX 1138 thread). The screenshot from your sample is 704x384. When I test-resized it to 720x316, it looked proper again. Is there a resizing issue here?
