I believe Stephen Backway explained that Bluray subtitles are always shown too
late - I can reproduce this with sample-dts-not-valid-dca-frame.m2ts, but not
with the re-encoded file (that has correct timing).

I did not test mkv, but it fails with the original file and mpeg, but succeeds
from avi to mpeg (which makes me think "start only so far in" is not the issue).

I had not much success with MPlayer with any files (except dvd/dvdnav) when
searching for samples yesterday.
