Samsung Smart TV + NAS WD My Book Live = mkv not support

Hello.
First of all i have to say that i've read lots of theme here and in internet about Samsung .mkv's support problems.
Second, i'm using serviio more than a year sharing to Samsung .mkv's and other media from my Mac and laptop with Win7x64.

I bought NAS WD My Book Live and i knew that it has old version of Twonky, which doesnt support mkv's, so i didn't use it at all. First my step was installing Serviio.
Serviio installed succesful.But I can play all media except .mkv files. Even audio streaming is good.
BTW i can see metadata of mkv, but when i'm trying to play it i see "File not support" message. Of course i know that my Samsung does support matroska codec.

I've turned my profile right -(Samsung TV/ player C/D - series) on both of my Samsung's(they are connected by LAN).
But not any .mkv file does play. I tried several. Here's mediainfo of 1 for example

  Code:

I have
NAS WD MyBook Live with serviio 0.6.1 installed, LAN connected with Samsung UE55D7000 and UE37D5500
FFMPEG version 0.7.13
java version "1.6.0_18"
zip, i know u helped here lots of people, please help me too.

[zip]

enable detailed log and make sure the C/D/E profile is indeed used for the incoming requests

For people who installed serviio with wiki instruction on NAS with Debian path for the log4j.xml is:
/usr/local/serviio/serviio-0.6.1/config/log4j.xml

enable detailed log and make sure the C/D/E profile is indeed used for the incoming requests

I did detailed log and sure that profile is correct (have green circle indicator), made reboot my NAS and no succes with mkv on UE55D7000. Didin't try on my other Sams yet.
Attached serviio.log if it can help

After these manipulations my UE37D5500 started to play .mkv files, but UE55D7000 didn't. I looked closely and found out that on UE55D7000 ip was another "generic dlna device", so i deleted him and now all my Samsung Smart TV's can play .mkv with Serviio 0.6.1 from my WD NAS.

Thank u, zip.
