I downloaded the MKV file on Uloz and it is corrupted.
Are you sure? Isn’t that posted as series of rar files? So which rar is corrupt?
I don’t know. The entire download when I use Winzip says that it is corrupt. I can watch the movie but I can’t skip chapters.
Does your download include the readme file? it include checksums, and that is the best way to determine if your file is corrupt.
