Apparently YOU do not understand black crush. Since you seem to complain a lot about me not being informative enough, here's a little slice of knowledge...
Black crush is a compression of dynamic range. Let's say your set displays shades of gray from pure black to whitey white... let's call those shades 0 to 255, 0 is black, 255 is white, and 128 is grey.
Now, let's imagine what would happen if you could only display digital shades 127-129... your entire picture would be 3 shades... 0-127 would be one shade, 128 the next, and 129-255 the third. You would be "compressing" all shades from 0-127 into one shade.
Now let's think of a more realistic case... you can display only from 16 to about 238... Shades of digital 0-16 would all be displayed as the same color. Anything from 0 to 16 will be pretty dark anyway... more of a shade of black, you might say, but now they are all the same shade of black. No adjustment to brightness can fix this issue, because they are simply all the same. This is what is called "black crush".
Most DVDs are mastered to utilize 16-238(ish) anyway (the NTSC standard), so it's no biggie. Some, however, like the Talented Mr. Ripley (good movie
) have a higher dynamic range and contain info from 0-16. If your set displays 0-16 all as the same shade, your picture will be degraded.
"How can I fix this?", you may ask. Well, on modern players like the Xbox 360 for example, there are settings to adjust the player's output range.
Let's look at the 360: There are 3 settings: Standard, Intermediate, and Expanded. Standard outputs 16-?, Expanded 0-255, and intermediate somewhere in between for those who are just guessing.
Play Mr. Ripley on your 360 on standard setting, and it will magically convert the DVD scale 0-255 to 16-238! You'll be able to view all those rich, dark details as the author intended! But set the Xbox to Expanded and... well, it will output 0-255 and that excellent dark tweed suit will look like just some cheap Sears Roebuck and Co. Poly-Mix.
