#171 VSFILTER: subs don't display for some OGM and MKV files

[Dom]

First, sorry if this is a basic request that doesn't
belong here.

I have the Matroska pack installed on my computer and
am slowly figuing out my way around ffdshow and
VSfilter. However, no matter what I seem to do or
try, I cannot get subtitles to display for a few .MKV
and .OGM files which I know have subtitles available.
When running the file, VSfilter tells me that it's
displaying subtitles, but nothing appears.

I'm at my wits end here, this is the first prolem I
haven't been able to solve on my own so far.

Thanks to anyone who can help me with this, and sorry
again if this is the wrong area for such problems.
