If you want, you can use tsMuxer to mux the MKV into an m2ts file. You won't lose quality, but you will lose subtitles if they're important to you. Then try playing back the m2ts files.

@icedtrip I can't seem to get tsMuxer (tsMuxerGUI) to open the Matrix rip. It comes up with a bunch of errors saying "Can't detect stream type. File name:"

I extracted a sample of the VC-1 inside MKV issue. I ran the sample through the test by itself. Below are links to the Media Info, XBMC Log (with debugging enabled), and the sample file itself.

@Observer, I believe this is the same issue you are having. I have the same problems with a rip of The Matrix.

@icedtrip Thanks for the clip. Your clip gives us a standard benchmark for anyone else who is having issues along side My Matrix Clip. I can't tell if the issue its same as yours just now.

Here is my equivalent XBMC.log For the Blood Diamond clip, and the post below for the Matrix Clip.

Initial observations that we are running different setups:

1. I'm running on an AppleTV "Mac OS X (8.8.2 i386)"
   
2. I'm running "Built on Mar 6 2011 (Git:ff701de)", a few days older
   
3. I'm running CrystalHD - BCM970015
   

I see that I get a:

CrystalHD: device open failed , returning(0x6)

And a lot of buffering...but given the failure above the rest is moot. Question is why did the Crystal HD Fail to open the device ? The rest of my setup is unchanged. Please let me know if I need to supply any additional information or re-test with different versions.

It's a starting point, it would be good to get an XBMC.LOG for anyone else running on an Apple TV with a CrystalHD - BCM970015 so we can get a more equivalent comparison.
