I handle them just as I do vob files.  As far as I'm aware, the only
necessary differentiation is the path provided for mplayer's
"-dvd-device".
For vobs it is
-dvd-device '/path/to/directory'  (containing vobs)
For isos
-dvd-device '/path/to/filename.iso

I'm only interested in the one language, so I regard multiple
subtitles as a nuisance.  As I've learned in this session I have to
deal with multiple soundtracks.  Currently I extract the possibles in
a for loop, then later merge the desired soundtrack with the video.
When it finishes the current batch I'm going to try Nicholas's patch,
but as I watch so much antique cinema I fear such may not include the
necessary info to directly identify the desired soundtrack.

I also use dd.
>From your "http://houghi.eu/s/DVD" Handbrake seems very different to
mencoder.  Does it do most of the decision-making for you?  For
example, things like combing and telecine, does it handle such
automatically?  My ripping script is entirely preoccupied with
ferreting out nitty-gritty details to build mencoder's command lines.
