Sorry for the double post.
Unfortunately, many of the same problems still persist(though, to a much lesser extent): some minor video issues and some major audio-video syncing issues.
@Dek Rollins I have informed the person who I mentioned in my first post (who also intended to upload the MKV 5.1 Only track) of the request of including the 2.0 and Mono mixes in the upload as well.
