[mythtv-users] Forced subtitles in mkv DVD rips.

I've just started ripping all my DVDs to mkv files for mythvideo, but
I'm a bit confused as to how forced subtitles work/should work.
My current process is
1. DVD -> ISO using 'DVD Decrypter' on Windows.
2. ISO -> MKV using Makemkv. At this point, I select just the main
title and pick one main soundtrack (normally DTS if available
otherwise 5.1 Dolby Digital). I also leave in all the 'English'
3. Use mkvinfo to identify the subtitle track numbers, rip them with
mkvextract and use vobsub2pgm so that I can look through the subtitles
I left in in step 2.
4. Finally, use mkvmerge to remux the mkv removing all subtitle tracks
(main English subtitle track, commentary subtitles etc.) leaving just
any forced subtitle track (and setting the forced flag) I discovered
in step 3.
A bit long winded, but this should produce what I want and no more.
According to the change log, new to myth 0.25 is support for
automatically displaying the forced subtitles. This doesn't seem to
be working for me.
I only get the forced subtitles if I manually select the subtitle from
the OSD. In the OSD forced subtitles are enabled, but don't display
without manually selecting them.
Is the issue due to me having removed the normal English subtitle track?
Are there easy ways of identifying which subtitle track is the forced
one? Makemkv doesn't seem to tell me. Ripping all of them and
converting them to images before manually examining them is time
Other than remuxing with mkvmerge, can anybody suggest an easier way
of changing the 'forced' flag on a mkv subtitle stream?
Many thanks for any help and suggestions.
