Playback OSD Menu is the one brought up by pressing 'M'? I only get 'Enable Subtitles' or 'Text Subtitles', both one which switch on the subtitles but only for that one single playback. Any ideas?


Yes, that's where you should find the Enable/Disable Forced Subtitles option.

Are you running 0.26?  There are several forced subtitle fixes/improvements that went into 0.26.

Do other players like vlc respect the forced subtitle track?  If not, maybe you created the mkv file incorrectly.  But if they do, then MythTV should be fixed.  It would help greatly if you could make a short sample available that demonstrates the problem, and open a new ticket.


Yes I'm running 0.26 from the mythbuntu repo. As for other players, I have played it in smplayer; smplayer displays the subtitles even when I choose the 'Forced Subtitles Only' option. mplayer from the command line with no options also displays them. I can't find a similar option in VLC, but it also displays the subtitles. mediainfo says the subtitle track has the Forced flag set, as does mkvinfo.

It's possible that I did the merge incorrectly, but it's only a case of merging an avi file and an srt file using the mkvmerge gui and setting the 'forced' option for the subtitle track - there isn't very much I could have done wrong :). It occurs to me that this makes the subtitle a 'plain text' subtitle, which is not what you would find on a DVD, so perhaps that is the issue? Or is there a 'preferred subtitle language' setting somewhere in mythtv, like there is in VLC, that would need to be set?

I'll open a ticket when I have time to prepare a sample.
