Bravia 55HX820 dont work with MKV

[tcviper]

Hello all,

Ive been an avid PS3MS user since 2008 but lately ive found that some devices dont work at all or only half.
If I play an MKV x264 1080p file on my PS3 (from Ps3MS) it works fine. If i try to play it to my Bravia HX820 I get stutter in the first second.

Any idea? It seems to be using the Bravia EX Profile, seems there is no other at the moment?

- Thank you,
Michiel
