# concatenate the VOB files... make sure you keep the order, and omit menus and
# other titles.
cat VTS_01_*.VOB > VTS_01_n.VOB

# inspect the big VOB
# using -analyzeduration and -probesize can help to detect streams that start
# later in the file, such as subtitles
ffprobe -analyzeduration 100M -probesize 100M -i VTS_01_n.VOB

# remux VOB to MKV
# '-fflags' will generate new timestamps, as many DVDs will throw a "Can't write
# packet with unknown timestamp" error. the '-map 0:*' arguments will include
# all video, audio and subtitle streams. '-c copy' will prevent any encoding,
# and simply remux the media
