Not all players support both 3D MVC MKV and 3D ISO containers, or well that it (for whatever reasons). All 3D-capable players do 3D ISO's well for the most part.

To sum it up:

• No stutters with MVC MKV's in RPi2/3 and Intel MVC. Get one of these two if MVC MKV's are important to you.
  
• Some stutters w/MVC MKV's in Zidoo X9S. 3D ISO's, which I think a majority of us use, is fine. Zidoo's X9S hasn't been out long, and they're working on issues.
  
• HiMedia has never claimed they support MVC MKV's, just 3D ISO's.
