Nope. Can't really be done without having access to the original file (i.e. the dvd) and resampling it. You may try turning your monitor's brightness up, but that will only help so much...
When the files are converted to AVI (MPEG, MOV, DIVX, etc), they use what is know as a "lossy" compression algorithm. That is, certain parts of each frame (29.7 Frames per second) is edited out to make the file smaller and much more manageable. Each pixel of each frame is sampled, and the value is a Red-Green-Blue binary value, there is no value for brightness.
Due to the compression, colors that are similar are counted as all the same color, so even if you brightened it with a program that decompressed, modified, and recompressed the file, the original data is long gone, you'd just have lighter grey spots instead of the solid black.
In short, you have a ****ty file, and if cranking your monitor's brightness and contrast up don't work, you're SOL.
