In fact I called that file an *.iso but I don't exactly know what it is.
I was trying to get rid of the errors/bad sectors that ARccOS adds to the
DVD so Icreated that file with 'ddrescue' like this:
$ ddrescue -b 2048 -n /dev/sr0 ~/dvdrips/rango.iso ~/logfile.txt
You can even check the message I posted on Reddit
https://www.reddit.com/r/Pirate/comments/6vtfe1/linux_cli_ripping_dvds/
This saved me from the reading errors I was getting without (at least
apparently) sacrificing any good data on the DVD.

Cool, I had already bumped into trancode

Let /dev/sr0 be the DVD reader and let 0 be the subtitle id you can to

So this would work for the subs...
While I am at it, would it make more sense to just use tccat/tcextract for
everything?
I took a look at http://howto-pages.org/dvdbackup/ and found these:
$ tccat -i /dvd -T 1,-1 > movie_name.vob     (to extract the VOB)
$ tcextract -i movie_name.vob -t vob -x mpeg2 > movie_name.m2v     (to
extract the M2V)
$ tcextract -i movie_name.vob -t vob -x ac3 -a 0 > monvie_name.ac3     (to
extract the AC3)
$ tcextract -i movie_name.vob -t vob -x ps1 -a 43 > subtitles.ps1     (to
extract SUBs)
$ tcprobe -i /dev/sr0 -T 1     (to get chapters' timecodes)

On paper it looks great but in fact it didn't work on my tests.
Apparently the extracted VOB was fine but the M2V and AC3 extracted from it
only have half of the movie. And I don't know if the project is still being
maintained. Their webpage gives me an error. Their ArchLinux package seems
to be updated frequently but it might just be due to repackaging
cosmetics...

There are more ideas and details in this page:

I will certainly take a look at their wiki which is one of the best
internet source of info on linux/opensource.
