I have a bunch of MKV files and Quicktime Player won't let me play them.
The weird thing is, I used to play Modern Family videos in MKV with perian, but I never knew. Recently, I got my hands on Game of Thrones and noticed it was in MKV, I didn't know I could already play it, so I googled and downloaded Perian, although I already had Perian... I tried playing Game of Thrones and it wouldn't work. It said I needed to check out some codecs i could download for Quicktime to play the files. It sent me to the apple support downloads and gave me a list of third party software i could download for different video extensions. But what is extremely stupid is, MKV isn't in one of the options. Seriously, how stupid is that? I then tried playing my Modern family files and they suddenly don't work either. This is very weird to me cause I was able to play these files before... I basically ****ed myself over downloading Perian again. I don't know why this would happen. I can't watch any MKV files. I uninstalled it and downloaded it again but to no avail. I tried Quicktime player 7 and it doesn't work either. All it says is: This file is not a movie file.
I downloaded VLC but it wouldn't play the files either. When I played the file on VLC nothing would appear. The loading bar would display the file name for a split second and then... nothing. This is all extremely frustrating to me cause I was able to play MKV files in the past with no problems, and then now I can't.
I'm on OS X Lion.

Both QuickTime Player with Perian installed and VLC will easily play .mkv files. It sounds like there's something wrong with the files.

I do not believe Perian has been updated with 10-bit support. I tend to use MPlayerX or VLC 1.3.0 nightly for MKV playback.

I have been trying to play MKV file on VLC and I can hear the background audio but none of the voices. Any solutions to this?

You could try out Mac Blu-ray Player. It's sort of free to try (has a watermark when playing BR movies). I like its ui and it plays everything I throw at it.
