It happens with almost every file I have. The issue is, when seeking forward
subtitles are shown instantly when they are supposed to be shown, after seeking
backward you need to wait 5-10 seconds before the subtitles will appear. I made
this against gstreamer-plugins-base-0.10.19.

It happens on other subtitle formats, too. It doesn't happen if I will comment
out the segment checking (but the performance is worse). Actually, disabling
the segment checking makes subtitles work _perfectly_, but at the expense of
performance. Enabling segment checking makes subtitles disappear for few
seconds after seeking.

It is very inconvenient, because microdvd parser is not checking for movie's
FPS (and it should, according to specification:
http://trac.annodex.net/wiki/MicroDVD, check this: "    * Frame rates need to
be converted into timings, thus it is necessary to obtain the frame rate of the
video to ensure the syncronisation of subtitling. "). So if user wants to check
if the subs are ok (if the framerate is ok), he needs to seek to few parts of
the movie, and it takes time, because subs are appearing after few seconds.
