I ripped my blu-ray of Thor The Dark World and I'm having trouble with the small section of alien language subtitles that I forgot to include when I ripped and encoded. I grabbed a copy of the subtitle srt and used Xmedia Recode to remux the track into the mkv. This worked, but the subtitles don't appear automatically - I have to manually select the track. Is there a way I can force them to be on? I've tried just about every setting I can think of in the subtitle section of XMedia Recode (convert, render, copy) and I have set the "forced subtitle" section to both yes and no. So far nothing I've tried has worked. I know I could re-encode the video and burn them in, but I feel like this should be possible without having to do that.
Any help would be appreciated!
