Black distortion/corruption in a movie

[kress]

I recently downloaded a movie which seems to have some kind of black distortion. Sometimes, during transitions and when characters move in the movie, there's a black corruption (I'm not sure what it's called) and you see black lines/cubes in certain points in the movie. Here are some screen shots:

Look at De Niro's napkin. It's full of these blocky black lines.

This one is much worse, the entire frame is corrupted.

Look at the man from the right. Check above his head for a lot black blocks.

This is another severe case, look at the right portion of the screen.

Yet another example, this time it's at different locations on the image.

As you might have guessed these captures are from The Untouchables.

Encoding info:

This black corruption is absolutely annoying. I can't watch a movie like that. None of my other movies do it (and I have a lot of movies). So I'm asking, is there anyway to fix this?

I recently downloaded a movie Please have a look at forum rule 6, which prohibits any posts referring to pirated content.

Also, I've deleted your other identical post, which is also against forum rules (cross posting: the posting of the same/similar message in multiple places).
