Cant play mkv files

[znoopy]

Hi there, got almost everything working but MKV (h264) is a no go
i have even bought the mpeg2 license, when i start the file
nothing happens. I have Raspberry Pi 2, using lastest Xbian
from webpage,

Config file looks like this, i did see a thread about changing gpu_mem but that
was an old thread for older version of raspberry.

initramfs initramfs.gz 0x1000000
gpu_mem_1024=256
gpu_mem_512=144
gpu_mem_256=100
initial_turbo=3
hdmi_ignore_cec_init=1
disable_overscan=1
disable_splash=1
decode_MPG2=xxxxxxxxxxxxxxxx

Anyone got a clue ? Ohh i using NFS share to run the files, xvid files works fine so i know all
that is working.
