I have some standard definition MKVs demuxed from commercial DVDs. They have multiple audio streams and 2 subtitle files. I open the video in V5 Pro, choose the english audio stream and save the video. The resulting video doesn't have subtitles. How do I keep the subtitles?
It's not easy. We'd have to write a whole parser and display routine for DVD subs. Not impossible, but not easy, and it's never really been a priority. We might do it someday, but it's not really at the top of the list.
