Is there a reliable way to convert MKVs containing vobsub (.sub) subtitles (which are very common in MKVs) to a format readable by AppleTV (like .srt)? I've tried everything I could find, but nothing has worked so far. I am trying to mux, not re-code the video stream (and the audio, unless it's DTS), but just change the wrapper to M4V (and embed the recoded subtitles). For MKVs containing vobsub subtitles, iFlicks fails, MP4Tools fails, Subler fails, FFMpegX fails.... Some crash, some just ignore the .sub file embedded in the MKV. Any suggestions other than doing this in Windows?
