On DVDs, the chapter information, like all the rest of the metadata
(language of the streams, palette of the subtitles, etc.), is stored in
the IFO files. MPlayer can read them when reading the DVD directly
through libdvdread/libdvdcss. FFmpeg, on the other hand, does not know
how to read DVDs directly, and the information is not present in the VOB
files.

Also, concatenating the VOB files like you did will not work correctly,
due to timestamps resets and menu data interleaved with the actual video
data. You can use the "dvd2concat" script distributed along with FFmpeg
to generate a concat script that only takes the relevant part of the VOB
files and controls the timestamp resets. It does not handle chapters,
but that could be added with a little effort.
