Not sure if you are talking about another step, but -dumpstream contains
all streams, in particular all audio and subtitle streams, and
you should be able to step through them during playback as usual.

That will not work after the dumpstream, the language information
is stored in DVD-specific structures and -dumpstream will lose that.
And the dumpstream will always copy all, so the option will not be
useful there either.
So in summary I don't think that will help :)
