MKV internal subtitles problem

[bil]

Hello!
Seems MKV's internal subtitles doesn't show when playing the video. The PMS sees them and they are present in the #--TRANSCODED--# directory ( for example: "MEncoder {audio: dca eng} {subs: hun}*" )
I don't have problem with the external subtitles. It doesn't matter if its AVI or MKV, they are showed flawless.
Can somebody help me on this issue?
Anyway the PMS is great!!
I almost forgot, i use PMS v1.03, Linux 2.6.27-gentoo-r7, MEncoder dev-SVN-r28058-4.3.2
