 VobSubs are subtitles on DVDs, which are pictures overlaid on the video image.
+Extract VOBSUBs using ''mencoder''. Will create ''dvd.idx'' and ''dvd.sub''.
+<code>
+mencoder dvd://1 -ovc copy -oac copy -vobsubout dvd -vobsuboutindex 0 -sid 0 -o /dev/null
+</code>
+Merge them all into a Matroska file:
+<code>
+mkvmerge -o dvd.mkv dvd.mp4 dvd.idx dvd.sub
+</code>
+=== Detecting VobSubs ===
+Note that ''ffmpeg'' and ''libav'' v 0.8.* will see the vobsubs and closed captioning streams with ''ffprobe'' or ''avprobe'', but any other higher version of ''avprobe'' (libav) will not.
