Please don't, if there's no other tool that can do the same things.

It's actually quite silly, there are so many open source tools that can
generate MPEG files and/or can take m2v, ac3, mp2, sub... files and mux
them, but so very few can generate MPEG2 files with dummy NAV packets!
And those that can generate such files (like mplex of mjpegtools) lack
other stuff (mplex/mjpegtools cannot mux subtitles).

I said in my previous message in this thread how you can extract m2v and
ac3 from VOB, and how to mux them back with mplex and also get the NAV
packets. It's also easy to extract subtitles, with a similar method,
using transcode:

cat bunch-of.vob | tcextract -x ps1 -t vob -a 0x20 > movie.vob

But how to mux that together with the m2v and ac3? (and also get the
dummy NAV stuff)

Here's another one:

tccat -i /dev/dvd -t dvd -P 1 | \
  tcdemux -A 0xe0,0x80,0x20 > movie.vob

This awesome transcode trick will get you a full title, but with only
one video angle, one audio track and one subtitles track - the bare
minimum.
However, the resulting vob has no dummy NAV packets, so dvdauthor cannot
accept it. The first tccat command (extracting the full title) preserves
the NAV stuff (and you can actually stop there and redirect it to a .vob
file that will get accepted by dvdauthor), but after piping it through
tcdemux (which picks from the title only one video / one audio / one
sub), the NAV placeholders are lost.

It would be great to have a tool that can take any arbitrary MPEG2 file
and add those dummy NAV packets.
Of course, it would be even greater if all applications that can
generate MPEG2 files would also have a command-line switch to add the
bogus NAV stuff. ;-) Otherwise it's kinda hard to author that MPEG2
content into a DVD.
