subtitles with matroska files

[prouty]

My problem:
_When I try to play mkv movies with bsplayer 2.0 (free), I can't see subtitles. Video is ok, sound is ok.
I saw few topicts relative to this problem so I follow advise some people have given.
I use matroska full pack with haali splitter, then I tried with the lite one without any result (no subtitles), then with matroska splitter (gabest ) but with this one I can't see the video.
_When I use haali splitter (include in matroska pack) I can see chapters and subtitles menus on right click over the video and i can change them but when I change the subtiles nothing happen.
_With matroska splitter (gabest) I don't have any video and I can't change chapters nor tracks.

Have you got any Idea???

my hardware config: AMD ATHLON XP2400+, nvidia geforce MX440,
