"Letters from Iwo Jima" has never been released in MKV format and as such is not going to be discussed here.

Given the dire and big fines for having a pirate copy I want you to consider asking via the REPORT OFFENSIVE POST link to have this discussion striken from the boards since you may be advertising to the RIAA and MPAA to "come get me."

Pirated goods are not viable subjects for discussion on the CNet forums.
